Three two (Antimony English antimony oxide trioxide) is a kind of white, cubic ultrafine powder is one of the most stable compounds of antimony. Molecular weight 291.5, melting point 656 degrees C, cubic crystal type (stable type) density is 5.3g/cm3. Three oxidation two aka antimony antimony white, as amphoteric oxide, insoluble in water, ethanol, dilute sulfuric acid and dilute nitric acid, but soluble in concentrated hydrochloric acid, sulfuric acid, tartaric acid and alkali solution.
Use:
As the flame retardant synergist applied to three oxidation two antimony polyvinyl chloride, polyethylene, polypropylene, polystyrene, ABS resin, polyester, polyurethane, epoxy resin and phenolic resin plastic products and polypropylene, polyester and other synthetic fibers. Flammable materials according to a certain proportion of adding halogenated flame retardants and antimony oxide three two synergist, the oxygen index of OI can significantly improve the combustion of materials, flame retardant effect, good price, is the most important inorganic flame retardant synergist.
It is used as a rubber filler, petrochemical industry passivation, glass manufacturing clarifier, ceramics, enamel industry colorants, photoelectric element production, solid lubricating material and ship antifouling coatings and medicine etc..
