Product name
Antimony sulfide - Sb2S3
Usage
As antimony sulfide mineral was known since ancient times and was used as a black makeup to dye eyelashes or eyelids. Today it is used in as an ingredient in matches, fireworks, in ruby red glass, as a dye for plastics and as a flame retardant.
Information
Antimony sulfide (Sb4S6 chemical formula or sometimes abbreviated to just Sb2S3) is a solid, very slightly soluble in water, but soluble in solutions of soluble sulfide or hydrosulfide. Reacts with strong acids to form salts antimonitých and release hydrogen sulfide, which causes a strong odor of rotten eggs. The hydroxides are dissolved to form antimonitanů. The air burns to form antimony trioxide Sb4O6 and sulfur dioxide SO2. It is a reducing agent which is oxidized to form compounds of Sb + V
Specifications
Gray-black, technical, fine crystalline powder of crude shiny Surma used in the manufacture of matches, antimony and its salts in fireworks, etc. also known as "Surma".
Sb2S3, after precipitation from cold Orange-red solution, after precipitation from solution or warm orange-red sulphide when heated, passes to šedočiernu modification.
It may contain lumps, or even excluded sulfur.
