antimony trioxide encyclopedia

Antimony - Wikipedia

Antimony is also used as an alloy in solder. 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 - 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.

Antimony - an overview | ScienceDirect Topics

The most significant use of antimony is the production of antimony trioxide for flame retardation (ATSDR, 1992; Butterman and Carlin, 2004). Antimony trioxide (+ 3 antimony), a white powder, is the single most important economic form, used primarily as a fire retardant. It is a stable substance that is not volatile and dissolves in water slightly.
