Antimony(III) Oxide Chemical Properties,Usage,Production

Chemical Properties

Antimony trioxide is a noncombustible, odorless, white crystalline powder.

Potential Exposure

It is used in flame-proofing, pigments and ceramics, to stain iron and copper; to decolorize glass; industrial chemical, dye, pigment, and printing ink.

Shipping

UN1549 Antimony compounds, inorganic, solid, n.o.s., Hazard Class: 6.1; Labels: 6.1-Poisonous materials, Technical Name Required.

Incompatibilities

Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides, halogenated acids, chlorinated rubber, bromine trifluoride. Reduction with hydrogen forms toxic antimony hydride.

Waste Disposal

Consult with environmental regulatory agencies for guidance on acceptable disposal practices. Generators of waste containing this contaminant (≥100 kg/mo) must conform with EPA regulations governing storage, transportation, treatment, and waste disposal.
