Antimony(III) sulfate – properties, industrial applications, and safety
Antimony(III) sulfate, also known as antimony trisulfate or Sb2(SO4)3, is an important inorganic compound with diverse industrial applications. In this blog post, we will take a closer look at the properties, uses, and safety aspects of this substance.
Properties of Antimony(III) Sulfate
Antimony(III) sulfate is a white, crystalline powder that is soluble in water. It has a molar mass of 403.56 g/mol and a density of 3.25 g/cm³. The melting point is 730 °C, and the boiling point is 850 °C.
The compound is stable under normal storage conditions, but can decompose when heated, releasing toxic fumes of sulfur dioxide and antimony oxides. Antimony(III) sulfate is a Lewis acid and reacts with bases to form antimonates.
Industrial Applications of Antimony(III) Sulfate
Antimony(III) sulfate is used in a number of industrial sectors:
Flame Retardants
One of the main applications is its use as a flame retardant in plastics, textiles, and other materials. Antimony sulfate increases fire resistance by reducing the release of flammable gases when heated.
