The largest end use for antimony trioxide is as a fire retardant in plastics, rubbers, textiles, paper and paints ( Mannsville Chemical Products Corp., 1981). Total US production has tripled since 1960 ( Mannsville Chemical Products Corp., 1981, 1985 Palencia & Mishra, 1986) and was approximately 19 000 tonnes in 1987 ( Llewellyn & Isaac, 1988).Īntimony trisulfide pigment is prepared by the addition of sodium thiosulfate solution to a solution of antimony potassium tartrate (tartar emetic) and tartaric acid or to a solution of another suitable antimony salt ( LeSota, 1978). The following countries produce antimony trioxide: Belgium, Bolivia, China, France, Guatemala, Mexico, South Africa, the UK, the USA and Yugoslavia. Antimony trioxide can be purified through serial vapour phase recrystallization ( Freedman et al., 1978 Mannsville Chemical Products Corp., 1981, 1985 Asarco, Inc., 1988a). ![]() ![]() Approximately 10–15% of US production occurs via this route. Antimony trioxide has also been isolated for many years as a by-product of lead smelting and production. Tetra- and pentoxides produce precipitate from the vapour as white and yellow powders, respectively. The stoichiometric addition of oxygen to the feed ore produces the desired product. The production of antimony trioxide occurs as a vapour-phase reaction at temperatures in excess of 1550☌. Antimony trioxide is typically produced by roasting stibnite ores, which are reported to contain 55% antimony. ![]()
