Antimony pentasulfide

Antimony pentasulfide is an inorganic compound with the formula Sb2S5. This material, which exists as the mineral stibnite, is a principal component of fireworks, antimony trisulfide, and the historic "butter of antimony".

Chemistry

Antimony pentasulfide can be prepared by heating antimony in the presence of sulfur. It reacts with strong oxidants to form antimony(V) compounds and with many metals to form sulfides. In its most common form, the pentasulfide is a polymer-like material, but it can also be prepared as a yellow amorphous powder.

Applications

Antimony pentasulfide is used in the production of fireworks, to create glitter effects and to increase the sensitivity of flash powder. It is also used in the production of lubricants, rubber products, and certain types of glass.

Safety

Antimony pentasulfide is not particularly toxic, but its dust can be irritating to the eyes and respiratory system. It is also a potential environmental hazard, as it can leach into soil and water systems.
