Zirconium(IV) Sulfate Tetrahydrate Powder Description

Zirconium(IV) sulfate tetrahydrate powder is a white crystalline powder with a relative density of 3.22 (16 °C). When heated to 135- 160 °C, it will lose three molecules of crystal water. When it is higher than 450 °C, it will lose all the chemical book crystal water. In addition, zirconium sulfate hydrate powder is soluble in water and sulfuric acid, slightly soluble in ethanol, and insoluble in hydrocarbons. When dissolved in water, a lot of heat is released, and the aqueous solution is strongly acidic. Besides, zirconium(IV) sulfate tetrahydrate powder is decomposed by alkali treatment or heating.
