Antimony Antimony is a chemical element with symbol Sb (from Latin: stibium) and atomic number 51. A lustrous gray metalloid, it is found in nature mainly as the sulfide mineral stibnite (Sb2S3). Antimony compounds have been known since ancient times and were powdered for use as medicine and cosmetics, often known by the Arabic name, kohl.

Antimony - Sb Very pure antimony is used to make certain types of semiconductor devices, such as diodes and infrared detectors. Antimony is alloyed with lead to increase lead's durability. Antimony alloys are also used in batteries, low friction metals, type metal and cable sheathing, among other products. Antimony compounds are used to make flame-proofing materials, paints, ceramic enamels, glass and pottery.

Occam's razor In the scientific method, parsimony is an epistemological, metaphysical or heuristic preference, not an irrefutable principle of logic or a scientific result. As a logical principle, Occam's razor would demand that scientists accept the simplest possible theoretical explanation for existing data.

Antimony pentafluoride Antimony pentafluoride is the inorganic compound with the formula Sb F 5.This colourless, viscous liquid is a valuable Lewis acid and a component of the superacid fluoroantimonic acid, the strongest known acid. It is notable for its Lewis acidity and its ability to react with almost all known compounds.he liquid contains polymers wherein each Sb is octahedral, the structure being described with the formula [SbF 4 (μ-F) 2 ] n ((μ-F) denotes the fact that fluoride centres bridge two Sb centres). The crystalline material is a tetramer, meaning that it has the formula [SbF 4 (μ-F)] 4.

- Appearance. Antimony is a semi-metal. In its metallic form it is silvery, hard and brittle. Uses. Antimony is used in the electronics industry to make some semiconductor devices, such as infrared detectors and diodes. It is alloyed with lead or other metals to improve their hardness and strength.A lead-antimony alloy is used in batteries.t is most often found as antimony(III) sulfide. It is extracted by roasting the antimony(III) sulfide to the oxide, and then reducing with carbon. Antimony can also be found as the native metal. China produces 88% of the world’s antimony.

- Melting Point: 631 degrees C. Antimony is a very brittle, crystalline metal which has a bluish-white color and a metallic shine. The metal is a poor conductor of heat and electricity. The metal is stable in air but will burn at a temperature close to its melting point, giving off white fumes of oxide.

- In general, parsimony is the principle that the simplest explanation that can explain the data is to be preferred. In the analysis of phylogeny, parsimony means that a hypothesis of relationships that requires the smallest number of character changes is most likely to be correct.n general, parsimony is the principle that the simplest explanation that can explain the data is to be preferred.

Antimony Element Facts We know that one of antimony’s minerals, stibnite (Sb 2 S 3), was used in Egyptian cosmetics four or five thousand years ago as a black eyeliner. (1). It is likely that the Roman author Pliny used the name stibium in the first century AD. We get the modern element symbol for antimony, Sb, from the word stibium. According to Pliny, the mineral stibnite was found most commonly among silver ores.

Type metal Antimony (Sb) melts at 630 °C. This highly crystalline metalloid, gives type metal its hardness and a much better and sharper cast from the matrix. It has a crystalline appearance while being both brittle and fusible. When alloyed with lead, it strengthens the alloy and improves casting detail.

Mineral Resource of the Month: Antimony Eighty percent of the world’s antimony is produced from two types of deposits — carbonate replacement deposits and gold-antimony epithermal deposits. The majority of antimony is consumed in the production of antimony trioxide (ATO), a compound used in flame-retardant materials. Combined with halogenated particles, ATO suppresses, reduces or delays the spread of flame.

- 1 Antimony is alloyed with other metals such as lead to increase its hardness and strength; its primary use is in antimonial lead, which is used in grid metal for lead acid storage batteries. ( 2 1). 3  Other uses of antimony alloys are for solder, sheet and pipe, bearing metals, castings, and type metal.
