Antimony trioxide is an inorganic compound with the formula sb203. Thenatural product is called antimony China, commonly known as antimony white.is a white crystalline powder, melting point 655°c, boiling point 1550°c, solublein concentrated hydrochloric acid-, sulfuric acid, alkali solution and hot tartaricacid solution, slightly soluble in water, dilute nitric acid- and dilute sulfuric acidmainly used as pigment, flame retardant, mordant, catalyst, can also be used tosynthesize antimony salt.
Antimony trioxide is an additive flame retardant, which is often used with other flame retardants and smoke suppressants, and the synergistic effect can be produced between the components.
At the initial stage of combustion, antimony trioxide is first melted, forming a protective film on the surface of the material to isolate the air, and reducing the combustion temperature through the internal endothermic reaction.
At high temperatures, antimony trioxide is vaporized, diluting the oxygen concentration in the air and thus playing a flame retardant role.
