Application
Antimony(V) sulfide serves a variety of purposes due to its distinctive properties. This orange to dark red powder is primarily used as a pigment and plays a crucial role in the vulcanization and coloring of rubber. Despite its insolubility in water, it is soluble in alkalies and alkali-metal carbonates, which makes it useful in specific industrial applications. Its composition may vary due to the presence of free sulfur, which raises doubts about the existence of a pure stoichiometric form, Sb2S5. Beyond its role in pigments and rubber, Antimony(V) sulfide is also involved in the manufacture of matches and fireworks, highlighting its versatility in different manufacturing processes.
