Physical description & handling notes

• Anhydrous zirconium sulfate is a colorless microcrystalline solid. Zirconium sulfate is also obtained as a white crystalline tetrahydrate, ZrSO4.4H2O. Both forms are soluble in water and noncombustible. It is corrosive to aluminum. It is used in chemical analysis, as an additive for lubricants, and for many other uses.
• Hygroscopic; [HSDB] Colorless solid; [CAMEO] White powder; [MSDSonline]
• White crystals
• Crystalline solid. Converted to monohydrate at 100 °C, to anhydrous form at 380 °C; solubility in water at 18 °C: 52.5 g/100 g solution. A solution at room temperature deposits a solid on standing. The more dilute the solution the more rapid the decomposition /Zirconium sulfate tetrahydrate/
• Soluble in water
• Slightly soluble in ethanol
