• 稳定性/保质期：

  如果按照规格正确使用和储存，则不会发生分解。该物质易溶于水，并释放大量溶解热，其水溶液呈酸性。在水中，硫酸锆会水解生成二氧化锆水合物（ZrO2·nH2O），形成白色絮状凝胶并具有胶体特性；而不溶于醇。随着溶液浓度的下降和pH值的增高，还会生成碱式硫酸锆。此外，该物质还具有良好的填充性和耐磨性。

制备方法与用途

概述

硫酸锆四水合物又称为四水合硫酸锆，是一种白色结晶性粉末，相对密度为3.22（16℃）。当加热至135～160℃时，它会失去三分子结晶水；而在高于450℃的温度下，则会全部失去结晶水。该物质能溶于水和硫酸，并微溶于乙醇，不溶于碳氢化合物。溶解于水中会产生大量热量，并形成强酸性溶液。通过碱处理或加热，它会发生分解。

用途

硫酸锆四水合物是一种无机化合物，可作为蛋白质的沉淀剂、催化剂和皮革鞣剂，同时也可用作减磨剂和润滑剂等。

  摘要：

  本发明涉及制备锆化合物的方法，经焙烧后形成氧化锆。该锆化合物的制备方法是将氨源添加到水合硫酸锆溶液中，使溶液pH在0.1至2.5范围内，优选在1.0至2.0范围内。从溶液中沉淀出的锆化合物呈结晶状，易于通过过滤收集，并且具有低水平的金属杂质。因此，本发明的方法可用于纯化锆化合物。本发明还包括锆化合物和纯化锆化合物（包括氧化锆）的方法。
