Gallium fulminate

Mercury, or 'quicksilver' as it is otherwise known, is a dense, toxic metal element that exists in liquid form at room temperature. At room temperature, mercury is a thick, silvery liquid with a very high density and low heat conductivity. Likely due to its unique properties, mercury was used, studied and prized by numerous civilizations, including the ancient Greeks, Romans, Chinese and Mayans.

For centuries, people believed that mercury possessed special healing properties and, consequently, used it as a diuretic and painkiller, as well as in medicines to treat various ailments from depression to syphilis. It has been used in cosmetics and as a decorative material.

Early on, it became clear that the mysterious liquid metal was toxic to humans because of the high instance of insanity and death in mercury mines. It, however, did not prevent experimentation. Between andBartolome de Medina developed the patio process for extracting silver from ores using mercury.

Later, during the California gold rush, variations of the patio process were used to extract gold. Attention was put on the metal's health effects on humans. In recent years, the United States and the European Union have put in place strict regulations on the production, use, and disposal of mercury.

Mercury is a very rare metal and is most often found in the ores cinnabar and livingstonite. Oxygen is pumped into the furnace, which combines with the sulfur, releasing sulfur dioxide and creating a mercury vapor that can be collected and cooled for further refinement as a pure metal.

By passing the mercury vapor through a water-cooled condenser, the mercury, which has a high boiling point, is the first to condense into its liquid metal form and collected. Mercury can also be leached from ores using sodium hydroxide and sodium sulfide. Recovery of the mercury is done by precipitation using aluminum or electrolysis. Through distillation, mercury can be purified to greater than The primary application for mercury metal in North America and Europe is in cathode cells, which are used for the production of caustic soda.

Production of coal-based PVC, like that produced in China, requires the use of mercury as a catalyst.

This newer scan, however, is not always the best scan in every situation. Published reports show about percent of neuroendocrine tumors have somatostatin receptors. Think of this receptor as a docking station for the hormone somatostatin. In healthy cells, these receptors are part of signaling system to regulate hormone secretions. For NETs that overexpress hormones, somatostatin receptors serve as a target for therapy given by oncologists and nuclear radiologists.

Synthetic somatostatin analogs, paired with radioactive agents, can bind to somatostatin receptors. This radiopharmaceutical can light up neuroendocrine cancer cells in a nuclear scan. Paul underwent a Gal scan at Roswell Park.

He asked his doctor for the scan because he had adverse reactions to traditional CT scans. For three to four days after a CT scan, he would experience chills, shakes, stiffness, and soreness. He underwent PRRT over the summer. At 63 he is now riding his bike and swimming regularly. The Ga scan is not offered at every cancer center. According to Dr.

Facebook Facebook Twitter Twitter. Updated January 19, Mercury is the only metal that is a liquid at standard temperature and pressure. The modern element symbol for mercury is Hg, which is the symbol for another name for mercury: hydrargyrum.

Hydrargyrum comes from Greek words for "water-silver" hydr- means water, argyros means silver. Mercury is a very rare element in the Earth's crust. It accounts for only about 0. Mercury generally is not allowed on aircraft because it combines so readily with aluminuma metal that is common on aircraft.

When mercury forms an amalgam with aluminum, the oxide layer that protects aluminum from oxidizing is disrupted. This causes aluminum to corrode in much the same way as iron rusts.

Mercury does not react with most acids. Mercury is a relatively poor conductor of heat. Most metals are excellent thermal conductors. It is a mild electrical conductor.

A Guide to Mercury Applications in Metalurgy

The electron configuration causes mercury to behave somewhat like a noble gas. Like noble gases, mercury forms relatively weak chemical bonds with other elements. It forms amalgams with all the other metals except iron. This makes iron a good choice to build containers for holding and transporting mercury.Silver fulminate AgCNO is the highly explosive silver salt of fulminic acid.

Silver fulminate is a primary explosivebut has limited use as such due to its extreme sensitivity to impact, heat, pressure and electricity. The compound becomes progressively sensitive as it is aggregated, even in small amounts; the touch of a falling featherthe impact of a single water droplet or a small static discharge are all capable of explosively detonating an unconfined pile of silver fulminate no larger than a dime and no heavier than a few milligrams.

Aggregating larger quantities is impossible due to the compound's tendency to self-detonate under its own weight. Silver fulminate was first prepared in by Edward Charles Howard in his research project to prepare a large variety of fulminates.

Along with mercury fulminateit is the only fulminate stable enough for commercial use. Detonators using silver fulminate were used to initiate picric acid inbut since have only been used by the Italian navy.

Silver fulminate occurs in two polymorphic formsan orthorhombic one and a trigonal one with a rhombohedral lattice. Fulminates are very toxic, about the same as cyanides. Like many silver salts, it darkens with light exposure. It is only slightly soluble in cold water and can be recrystallized using hot water. This compound can be prepared by pouring a solution of silver nitrate in nitric acid into ethanolunder careful control of the reaction conditions, to avoid an explosion.

Another way to make silver fulminate is to react silver carbonate with ammonia in solution. Silver fulminate also forms when nitrogen oxide gas is passed through a solution of silver nitrate in ethanol. Silver fulminate can be prepared unintentionally, when an acidic solution of silver nitrate comes in contact with alcohol. Silver fulminate, often in combination with potassium chlorateis used in trick noise-makers known as "throw-downs", "crackers", "snappers", "whippersnappers", "pop-its", or "bang-snaps", a popular type of novelty firework.

They contain approximately milligrams of fine gravel coated with a minute quantity approximately 80 micrograms [8] of silver fulminate. When thrown against a hard surface, the impact is sufficient to detonate the tiny quantity of explosive, creating a small report from the supersonic detonation. Snaps are designed to be incapable of producing damage even when detonated against skin due to the buffering effect provided by the much greater mass of the gravel medium.

It is also the chemical found in Christmas crackers [9] having first been used for that purpose by Tom Smith in The chemical is painted on one of two narrow strips of card, with abrasive on the second.

When the cracker is pulled, the abrasive detonates the silver fulminate. Silver fulminate is often confused with silver nitridesilver azideor fulminating silver. While it may be a synonym of silver fulminate, it may also refer to the nitride or azide, the decomposition product of Tollen's reagentor an alchemical mixture, which does not contain the fulminate anion.

An explosive is a reactive substance that contains a great amount of potential energy that can produce an explosion if released suddenly, usually accompanied by the production of light, heat, sound, and pressure.

An explosive charge is a measured quantity of explosive material, which may either be composed solely of one ingredient or be a mixture containing at least two substances. It is highly sensitive to friction, heat and shock and is mainly used as a trigger for other explosives in percussion caps and blasting caps.Mercury is a chemical element with the symbol Hg and atomic number Mercury occurs in deposits throughout the world mostly as cinnabar mercuric sulfide.

The red pigment vermilion is obtained by grinding natural cinnabar or synthetic mercuric sulfide. Mercury is used in thermometersbarometersmanometerssphygmomanometersfloat valvesmercury switchesmercury relaysfluorescent lamps and other devices, though concerns about the element's toxicity have led to mercury thermometers and sphygmomanometers being largely phased out in clinical environments in favor of alternatives such as alcohol - or galinstan -filled glass thermometers and thermistor - or infrared -based electronic instruments.

Likewise, mechanical pressure gauges and electronic strain gauge sensors have replaced mercury sphygmomanometers. Mercury remains in use in scientific research applications and in amalgam for dental restoration in some locales. It is also used in fluorescent lighting.

Electricity passed through mercury vapor in a fluorescent lamp produces short-wave ultraviolet lightwhich then causes the phosphor in the tube to fluorescemaking visible light.

Mercury poisoning can result from exposure to water-soluble forms of mercury such as mercuric chloride or methylmercuryby inhalation of mercury vapor, or by ingesting any form of mercury. Mercury is a heavy, silvery-white liquid metal. Compared to other metals, it is a poor conductor of heat, but a fair conductor of electricity. The coefficient of volume expansion is Solid mercury is malleable and ductile and can be cut with a knife. A complete explanation of mercury's extreme volatility delves deep into the realm of quantum physicsbut it can be summarized as follows: mercury has a unique electron configuration where electrons fill up all the available 1s, 2s, 2p, 3s, 3p, 3d, 4s, 4p, 4d, 4f, 5s, 5p, 5d, and 6s subshells.

Because this configuration strongly resists removal of an electron, mercury behaves similarly to noble gaseswhich form weak bonds and hence melt at low temperatures. The stability of the 6s shell is due to the presence of a filled 4f shell.

Silver fulminate

An f shell poorly screens the nuclear charge that increases the attractive Coulomb interaction of the 6s shell and the nucleus see lanthanide contraction. The absence of a filled inner f shell is the reason for the somewhat higher melting temperature of cadmium and zincalthough both these metals still melt easily and, in addition, have unusually low boiling points. Mercury does not react with most acids, such as dilute sulfuric acidalthough oxidizing acids such as concentrated sulfuric acid and nitric acid or aqua regia dissolve it to give sulfatenitrateand chloride.

Like silver, mercury reacts with atmospheric hydrogen sulfide. Mercury reacts with solid sulfur flakes, which are used in mercury spill kits to absorb mercury spill kits also use activated carbon and powdered zinc. Mercury dissolves many metals such as gold and silver to form amalgams. Iron is an exception, and iron flasks have traditionally been used to trade mercury. Several other first row transition metals with the exception of manganesecopper and zinc are also resistant in forming amalgams.

Other elements that do not readily form amalgams with mercury include platinum. Mercury readily combines with aluminium to form a mercury-aluminium amalgam when the two pure metals come into contact. Since the amalgam destroys the aluminium oxide layer which protects metallic aluminium from oxidizing in-depth as in iron rustingeven small amounts of mercury can seriously corrode aluminium.Silver fulminate AgCNO is the highly explosive silver salt of fulminic acid.
