Description
Synthetic antimony trioxide, produced by roasting Antimony ore then mixing with Barium sulfate, was introduced as an artists' pigment called antimony white in 1920. Antinomy white was sold under the name Timonox. It is inert, has good hiding power and low oil absorption. Since it is darkened by Hydrogen sulfide, it is often mixed with Zinc oxide which has preferential absorption for that gas (Gettens and Stout 1966). Some samples may contain senarmonite and/or valentinite, two known mineral forms of antimony oxide. Octahedral arsenic oxide may also be present as an impurity. Antimony trioxide is used as a white pigment and opacifiers in enamels and glasses. It is also used to flameproof textiles, paper and plastic.
