Anwendungen
BeschreibungThis hard shiny metal is often alloyed to other elements. It is used in various industrial fields, such as those making or using batteries, printing machines, bearing, textiles, and ceramics. It caused positive patch test reactions in two workers in a ceramics industry.
OccurrenceAntimony trioxide occurs in nature as minerals, valentinite [1317-98-2] and senarmontinite [12412-52-1]. It is used as a flame retardant in fabrics; as an opacifier in ceramics, glass and vitreous enamels; as a catalyst; as a white pigment in paints; as a mortar in the manufacture of tartar emetic; and in the production of metallic antimony.
Verwendenmanufacture of tartar emetic; as paint pigment; in enamels and glasses; as mordant; in flame-proofing canvas.
Darstellung
synthetischeAntimony trioxide is obtained by roasting stibnite:2 Sb2S3 + 9 O2 → 2Sb2O3 + 6SO2Temperature and air feed is carefully controlled in the process to suppress any formation of antimony tetroxide (Sb2O4). Antimony trioxide is separated from any arsenic trioxide (As2O3) that may be present as an impurity by volatilization, as the latter is much more volatile than the former. It may be also prepared by alkaline hydrolysis of antimony trichloride and subsequent dehydration of hydrous oxide under controlled heating (rapid or vigorous heating may partially oxidize Sb(III) to Sb(V).Antimony trioxide also may be made by heating the metallic element with oxygen or air. The volatilizing trioxide is condensed and collected.
