Nov 21, 2020· Antimony is a chemical element with atomic number 51 which means there are 51 protons and 51 electrons in the atomic structure. The chemical symbol for Antimony is Sb. Antimony is a lustrous gray metalloid, it is found in nature mainly as the sulfide mineral stibnite.
The Mineral antimony. Antimony is a native element that can occur in a natural state, but it is rarely pure. It almost always contains some arsenic, and may also contain traces of silver, iron, and sulfur. On a fresh or preserved surface, Antimony has a tin-white color with a slight blue tinge. Otherwise, it is dark gray due to tarnish.
Jul 29, 2019· Properties . The melting point of antimony is 630.74°C, the boiling point is 1950°C, specific gravity is 6.691 (at 20°C), with a valence of 0, -3, +3, or +5. Two allotropic forms of antimony exist; the usual stable metallic form and the amorphous gray form. Metallic antimony is extremely brittle. It is a bluish-white metal with a flaky crystalline texture and metallic luster.
Antimony is about one-fifth as abundant as arsenic, contributing on the average about one gram to every ton of the Earth's crust. Its cosmic abundance is estimated as about one atom to every 5,000,000 atoms of silicon. Small deposits of native metal have been found, but most antimony occurs in the form of more than 100 different minerals.
Apr 06, 2009· Antimony is an element, so the only substance that can be found in it is antimony. Antimony is itself a toxin.
Antimony is a lustrous gray metalloid, it is found in nature mainly as the sulfide mineral stibnite. 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, an SB element is described as a chemical element. A lustrous gray metalloid is found mainly in nature as the sulfide mineral stibnite (Sb 2 S 3).Antimony compounds are known since ancient times and were powdered to use in cosmetics and medicines, often known by the Arabic name kohl.
Studies have also found that antimony can cross the placenta resulting in fetal exposure and can accumulate in breast milk [141]. Metabolism of antimony mainly consists of interconversion between the trivalent and pentavalent states, with reduction of antimony(V) occurring in the presence of glutathione or cysteinylglycine [138, 139].
In flame retardants, this is mainly because of high antimony prices prompting substitution of antimony, and legislative and requirements forcing changes to flame retardant formulas. In batteries, lead-calcium-tin alloys are increasingly used instead of antimonial lead in battery grids for sealed-for-life maintenance-free automotive batteries ...

Antimony is an important mineral commodity used widely in modern industrialized societies. The element imparts strength, hardness, and corrosion resistance to alloys that are used in many areas of industry, including in lead-acid storage batteries. Antimony's leading use is as a fire retardant in safety equipment and in goods, such as mattresses.
Some antimony is produced as a by-product of smelting ores of other metals, mainly gold, copper and silver, in countries such as the United States, Canada, and Australia. Important amounts of antimony are yielded as a by-product of copper and silver mining. Numerous …
To obtain high-purity antimony, zone refining is carried out in an atmosphere of inert gas, or antimony is obtained from previously purified antimony trioxide or antimony trichloride. Uses.

Antimony is a lustrous gray metalloid, it is found in nature mainly as the sulfide mineral stibnite. Antimony compounds have been known since ancient times and were powdered for use as medicine and cosmetics. The industrial methods for refining antimony are roasting and reduction with carbon or direct reduction of stibnite with iron.
Contact with antimony occurs in a variety of ways, and as it is a common element in the surface of the earth it may accompany exposures to many different materials. Antimony has been identified in at least 114 different ores, and has even been found in meteorites.
The intermetallic compounds AsSb, GaSb and InSb have found some applications in electronics. The sulphide Sb2S3 is one of the components of brake linings. Recycling. Antimony can be recovered in the residues from the lead refining process. The main end-of-life recycling option is from spent lead-acid batteries mainly recovered from old vehicles.
