Product Application of Diantimony trioxide CAS#1309-64-4
Antimony oxide, Sb2O3, is a nonreactive white pigment prepared from metallic antimony using a similar technique to that used for the preparation of zinc oxide.
Antimony oxide is widely used in the preparation of fire retardant paint in conjunction with chlorine containing resins. On exposure to fire, the chlorine gas liberated by decomposition of the resin component of the paint film reacts with the antimony oxide to produce a vapor of antimony chloride that blankets the flames. Antimony oxide is also used to modify the heavy chalking characteristics of anatase form of titanium oxide.
