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.
May 6, 2021 · The U.S. today is almost entirely reliant on China for its supplies of antimony, a rare earth mineral that is essential to the success of wind power, solar power and the next generation battery...
May 22, 2024 · Antimony, a metallic element belonging to the nitrogen group (Group 15 [Va] of the periodic table). Antimony exists in many allotropic forms. It is a lustrous silvery bluish white solid that is very brittle and has a flaky texture.
Antimony is made from stibnite by heating it with air. This makes antimony trioxide. Since it gets so hot, the antimony trioxide is evaporated. 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 not an abundant element but is found in small quantities in over 100 mineral species. It 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.
May 22, 2024 · Antimony - Properties, Reactions, Uses: The most stable form of elemental antimony is a brittle silvery solid of high metallic luster. Electrolytic deposition of antimony under certain conditions produces an unstable amorphous form called “explosive antimony,” because, when bent or scratched, it will change in a mildly explosive manner to ...
Antimony, atomic symbol Sb, has atomic number 51 on the periodic table. It lies to the right of tin, and to the left of tellurium. It lies below arsenic, and above bismuth, and it has properties similar to both of those elements. Antimony has an electron configuration of [Kr]4d 10 5s 2 5p 3.
