Antimony trisulfide (Sb 2 S 3) is found in nature as the crystalline mineral stibnite and the amorphous red mineral (actually a mineraloid) [3] metastibnite. [4] It is manufactured for use in safety matches , military ammunition, explosives and fireworks.
Antimony is a chemical element; it has symbol Sb (from Latin stibium) and atomic number 51. A lustrous grey metal or metalloid, it is found in nature mainly as the sulfide mineral stibnite (Sb 2 S 3). Antimony compounds have been known since ancient times and were powdered for use as medicine and cosmetics, often known by the Arabic name kohl. [11]
Stibnite, sometimes called antimonite, is a sulfide mineral with the formula Sb 2 S 3.This soft grey material crystallizes in an orthorhombic space group. [6] It is the most important source for the metalloid antimony. [7]
Antimony sulfide may refer to either of two compounds of antimony and sulfur: Antimony trisulfide, Sb 2 S 3; Antimony pentasulfide, Sb 2 S 5, known as antimony red
Antimony(III) oxide has suspected carcinogenic potential for humans. [13] Its TLV is 0.5 mg/m 3, as for most antimony compounds. [14] Before 2021, no other human health hazards were identified for antimony(III) oxide, and no risks to human health and the environment were identified from the production and use of antimony trioxide in daily life.
Prices of antimony, used in semiconductors and military applications, hit all-time highs, currently trading between $39,500-40,000 per metric ton in Rotterdam as of Dec. 31. China's export ban to ...
China is a major producer of antimony, and some U.S. policymakers have worried about being overly dependent on China as a source. The mineral's uses include flame retardants, batteries, night ...
Antimony (51 Sb) occurs in two stable isotopes, 121 Sb and 123 Sb. There are 37 artificial radioactive isotopes, the longest-lived of which are 125 Sb, with a half-life of 2.75856 years; 124 Sb, with half-life 60.2 days; and 126 Sb, with half-life 12.35 days. All other isotopes have half-lives less than 4 days, most less than an hour.
