Antimony trioxide nature

Antimony trioxide cubic crystal; the temperature of 656° C, the about body of 5.2; gender, acrid able acid; acrid in acid; the solubility in baptize is 0.002 grams of /100 ml of water. Three two antimony oxide in air acrimonious to 300 ~ 400 ° C yellow, accessible antimony antimony (III ) ( Sb Ⅲ( SbVO4 ) ), the about body of 5.82, able calefaction and absolution oxygen, became the three two antimony oxide. Three two blaze antimony and acrid melting, M2SbⅢ( SbⅢ O4 ) alkali (M is a monovalent metal ). Sb2O3 breath atom is two polymer Sb4O6, college than 800 °C break of Sb2O3, 1800 ° C about complete dissociation. Three two blaze antimony from antimony metal in the melting in the air or agitation system.

Antimony trioxide is acclimated as a blaze retardant and can be broadly acclimated in polyethylene, polypropylene, polystyrene, PVC, nylon, engineering plastics ( ABS ), rubber, paint, coatings, constructed resin, cardboard abstracts such as blaze retardant. As a defoaming abettor acclimated for melting the bottle bright bubble, acclimated as a agitator in polyester fiber. For apply and bowl articles for accoutrement agent, whitening agent. For petroleum abundant oil, residue, catalytic cracking, catalytic reforming action for passivating agent.
