Antimony trioxide

Antimony trioxide (also referred to as antimony oxide, commonly known as antimony white) molecular formula: Sb2O3 molecular weight: 291.5 Antimony trioxide is one of the inorganic flame retardants that have been used for a long time. It is mainly used as a flame retardant synergist to cooperate with halogen-containing compounds. It plays a flame retardant role in their thermal decomposition process and can replace some halogen compounds. It can be applied to plastics, rubber, chemical fiber, enamel, pigment, paint, glass, glass, electronics and other industries.

2.Nature：

Antimony trioxide (English name Antimony trioxide) is a pure white, cubic crystal system ultrafine powder, is the most stable compound of antimony. Molecular weight 291.5, melting point 656 ℃,The cubic crystal form (stable form) has a density of 5.3g/cm3. Antimony trioxide, also known as antimony white, is an amphoteric oxide, insoluble in water, ethanol, alkene sulfuric acid and alkene nitric acid, but soluble in concentrated hydrochloric acid, sulfuric acid, strong alkali and tartaric acid solution.

　3. Use
Antimony trioxide is one of the early used inorganic flame retardants, mainly as a flame retardant synergistic agent with halogen compounds, in their thermal decomposition process play a flame retardant role, and can replace part of the halogen compounds, can be used in plastics, rubber, chemical fiber, enamel, paint, glass, electronics and other industries.
