Description. Antimony trioxide is the inorganic compound with the formula Sb2O3. It is the most important commercial compound of antimony. It is found in nature as the minerals valentinite and senarmontite. Antimony trioxide is mainly produced via the smelting of stibnite ore, which is oxidised to crude Sb2O3 using furnaces operating...
