    General Information. Antimony trioxide (Sb 2 O 3) is a slightly soluble, white crystalline powder. [] It is produced by smelting antimony-containing ores [] or reacting antimony trichloride with water. [] Antimony is not abundant in the earth’s crust. [] Antimony trioxide may also be referred to as diantimony trioxide (DAT), antimony oxide, or in manufacturing as antimony white. []
