Description: zirconium sulfate is a white crystalline powder irritant. Mainly used as a protein precipitating agent, titanium dioxide coated, white leather, leather and other leather tanning wrinkle agent, also used as a catalyst, by grinding. Product Character: white crystalline powder or crystalline solid, hygroscopic. Become heated to 100 ℃, containing part of crystal water, 380 ℃ time into anhydrous. Soluble in water (18 ℃ water solubility of 52g / 100g), insoluble in ethanol, aqueous acidic to litmus. Aqueous solution at room temperature, after the long home 4ZrO2? 3SO3? 15H2O precipitation, the more dilute solution more easily precipitated. The relative density (d16) 3.22. Mp 410 ℃ (anhydrous, decomposition). Low toxicity, the median lethal dose (rat, oral) 3500mg / kg. Irritation. Uses: catalyst supports, amino acids and proteins precipitating agent, titanium dioxide coated, leather tanning agent.
