Estimates of the abundance of antimony in the Earth's crust range from 0.2 to 0.5 parts per million. Antimony is chalcophile, occurring with sulfur and the heavy metals, lead, copper, and silver. Over a hundred minerals of antimony are found in nature. Stibnite (Sb 2 S 3 ) is the predominant ore mineral of antimony.

Bismuth is a brittle, silvery-green metal that has a low melting temperature and high specific gravity. Being both stable and non-toxic, bismuth is often used as a replacement for toxic metals such as antimony, cadmium, lead, and mercury.

Metallic antimony is an extremely brittle metal of a flaky, crystalline texture. It is bluish white and has a metallic lustre. It is not acted on by air at room temperature, but burns brilliantly when heated with the formation of white fumes.

For example, arsenic and antimony are decomposed by mercury. ... but an excessive addition or presence is a problem because the metallic product can be brittle ...

Antimony is widely used in alloying to increase hardness and mechanical strength. Antimony is used in the semiconductor industry for infrared detectors, Hall-effect devices, and diodes. The metal and its compounds also used in batteries, bullets, cable sheathing, flame-proofing compounds, glass, ceramics, paints, and pottery.

Pure antimony metal is silver gray/white and brittle. Although actually a metal, like germanium and tellurium (of which more in forthcoming articles), antimony is also termed a metalloid.

Antimony is nonmalleable, hard and brittle and can be crushed to a powder. Compared with metals, antimony is a poor conductor of electricity and heat. ... The name antimony was derived from the Greek words, "anti," meaning not, and "monos," meaning alone, because antimony is normally found in complex ore bodies.

Antimony is a silvery-white, shiny element that looks like a metal. It has a scaly surface and is hard and brittle like a non-metal. It can also be prepared as a black powder with a shiny brilliance to it. The melting point of antimony is 630°C (1,170°F) and its boiling point is 1,635°C (2,980°F).

Antimony is a chemical element. ... It is brittle, soft, and shiny. ... Other metal oxides in the stibnite ore do not evaporate. The antimony trioxide gas is condensed in a container. The antimony trioxide is then heated with carbon to make carbon dioxide and antimony.

Antimony is a silvery-gray, brittle semi-metal with chemical symbol Sb and atomic number 51. It rarely occurs in nature as a native element, but is found in a number of different minerals, the most important of which is Stibnite (Sb2S3).

AN'TIMONY, noun [Low Latin antimonium.]. Primarily, a metallic ore consisting of sulphur combined with a metal; the sulphuret of antimony the stibium of the Romans and of the Greeks. It is a blackish mineral, which stains the hands, hard, brittle, full of long, shining, needlelike striae.

Named from the Greek words meaning "not alone", antimony is a metalloid element that primarily is found as a very brittle bluish-white metallic substance.

Elemental antimony is a brittle, silver-white shiny metalloid. When slowly cooled, molten antimony crystallizes in a trigonal cell, isomorphic with the gray allotrope of arsenic . A rare explosive form of antimony can be formed from the electrolysis of antimony trichloride .

Antimony is also found in chemical compounds such as antimony (II) sulfide. With regards to its properties, antimony is a poor conductor of both heat and electricity. Described as brittle, it can ...

Antimony in its elemental form is a silvery white, brittle crystalline solid that exhibits poor electrical and heat conductivity properties. Commercial forms of antimony are generally ingots, broken pieces, granules, and cast cake.

Bismuth is a chemical element with symbol Bi and atomic number 83. It is a pentavalent post-transition metal and one of the pnictogens with chemical properties resembling its lighter homologs arsenic and antimony.Elemental bismuth may occur naturally, although its sulfide and oxide form important commercial ores. The free element is 86% as dense as lead.It is a brittle metal with a silvery ...

Antimony is a minor ore of the element antimony, although most antimony comes from antimony compounds (namely Stibnite), which are much greater in abundance. Antimony has a very interesting property: It is similar to water, in that instead of contracting when …

1. Introduction. Ore deposits are the product of crustal evolution in specific areas and at particular stages. Hence, a full understanding of the local geological setting is a prerequisite in studying the genesis of ore deposits (Hedenquist and Lowenstern, 1994, Simmons and Brown, 2006, Zhu et al., 2007b, Hou et al., 2008, Baker et al., 2010). ...

The major use of antimony is in lead alloys - mainly for use in batteries - adding hardness and smoothness of finish. The higher the proportion of antimony in the alloy, the harder and more brittle it …

The natural sulfide of antimony was known and used in Biblical times as medicine and as a cosmetic. Antimony in its elemental form is a silvery white, brittle crystalline solid that exhibits poor electrical and heat conductivity properties. Commercial forms of antimony are generally ingots, broken pieces, granules, and cast cake.

Elemental antimony is present in relatively small amount owing to high reactivity of antimony with sulfur, lead, silver and copper.Stibnite is the commonly used ore for extracting antimony, ores of antimony are crushed and then antimony is hand sorted from the crushed ore.

Antimony (Sb) is a hard, brittle, silver-white metal with a relatively high specific gravity (6.69) and a relatively low melting temperature. Antimony is a constituent in some alloys. The presence of this metal hardens the alloy, lowers the melting point, and decreases contraction during solidification.

The principal ore is stibnite, a sulfur compound known since early times there are extensive deposits in China. Antimony is often found in other ores as well, e.g., silver, copper, and lead. Antimony is often found in other ores as well, e.g., silver, copper, and lead.

Antimony is a silvery-white metal that is found in the earth's crust. Antimony ores are mined and then either changed to antimony metal or combined with oxygen to form antimony oxide.
