In this process, antimony metal or ores is melted in a furnace to give ATO vapors. The vapors are quenched with air and cooled to convert the vapor to white powder. These powders are further filtered to give antimony trioxide powder. Direct process. In this process, crude antimony oxide is roasted in the presence of air to give ATO vapors.

Antimony trioxide, is the most important commercial compound of antimony. It is found in nature as the minerals valentinite and senarmontite and is mainly produced via the smelting of stibnite ore, which is oxidised to crude Sb2O3 using furnaces operating at approximately 850 to 1,000 °C. Antimonious oxide is widely used as a flame retardant
