化合物简介
Zirconium (IV) hydroxide is often called hydrous zirconia. It has an indeterminate chemical formula often described as ZrO2.nH2O. The formula ZrO2.2H2O being written as Zr(OH)4 gives rise to its description as a hydroxide. The compound is a toxic, amorphous white powder which is insoluble in water, but is soluble in dilute mineral acids.

生产方法及用途
生产方法
1.中和法以氧氯化锆及氨水为原料制备氢氧化锆:在常温搅拌下向0.2~0.
3 mol/L的高纯氧氯化锆溶液中徐徐加入纯氨水,将溶液进行中和,中和至pH=8~85时,再用纯水洗涤至无氯离子(Cl-)为止,经过滤,分离,将滤饼于12
0 ℃干燥后即得产品。

2.由氢氧化钠溶液加锆盐溶液而制得。
用途
主要用于制备锆及锆化合物,也用于塑料,橡胶,离子交换树脂等行业的填充剂,催化剂,除臭剂及颜料等。常用于合成二氧化锆、玻璃抛光、颜料等。
