Antimony - Antimony - Properties and reactions: The most stable form of elemental antimony is a brittle, silvery solid of high metallic lustre. 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 the more stable, metallic form.
Oct 27, 2020· Highly purified antimony is used in semiconductor technology to prepare the intermetallic compounds indium, aluminum, and gallium antimonide for diodes and infrared detectors. Antimony compounds (especially the trioxide) are widely used as flame retardants in paints, plastics, rubber, and textiles.
Antimony is believed to be found in the Earth's crust at about 0.2 to 0.5 parts per million. It is found in over 100 different minerals. Antimony is occasionally found in its pure form, but is most commonly found in the mineral stibnite. China is typically the top global producer of antimony, extracting between 84% and 88% of the supply.
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. It is the most important source for the metalloid antimony. The name is from the Greek στίβι stibi through the Latin stibium as the old name for the mineral and the element antimony.

ANTIMONY SULFIDE presents a serious fire risk if exposed to oxidizing agents. Crystals burn with a blue flame when heated in air [Mellor 9:522 ]. Emits toxic antimony and sulfur oxide fumes if heated to high temperatures. Reacts with concentrated solutions of chloric acid with incandescence [Mellor Supp. II Part I:584 1956].
Feb 08, 2016· The history of antimony goes back to as early as 3100 BC, when it was used by the Egyptians as cosmetic in the form of black Sb 2 S 3 [].Antimony was later used by alchemists in the form of antimony oxychloride SbOCl, which acted as a powerful emetic and thus became known as "mercury of life" or "algarot" [].The etymology of the current name "antimony" is still subject of discussion.
Antimony Properties. Antimony is a Block P, Group 15, Period 5 element. The number of electrons in each of Antimony's shells is 2, 8, 18, 18, 5 and its electronic configuration is [Kr] 4d 10 5s 2 5p 3.In its elemental form, CAS, antimony has a silvery lustrous gray appearance.

It's by far the most abundant element in its group in the periodic table and yet it is the last member of its family to be discovered. The other elements in its group, phosphorus, arsenic, antimony and bismuth, had all been discovered, used and abused at least 100 years before nitrogen was known about.

Antimony is a brittle, fusible, crystalline solid. It is easily powdered. Antimony also has the unusual property that (like water) it expands as it freezes. Four other elements expand when they freeze; silicon, bismuth, gallium and germanium. In addition to the usual form of antimony, there are two allotropes: yellow crystalline and amorphous black.
Oct 27, 2020· 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. It occurs chiefly as the gray sulfide mineral stibnite.
