补充资料:化学共沉淀法
分子式:
CAS号:

性质:将适当的原料按化学式计量配比溶于一定的溶剂中配成含有一定浓度的多种可溶性阳离子的盐溶液,然后加入适当沉淀剂(如OH-,CO-,C2O42-等),控制一定pH值,使各种阳离子同时形成不溶性氢氧化物、碳酸盐或草酸盐的沉积物。对沉淀物经后处理而得到所需的粉体的一种方法。沉积剂的种类和用量的适当选择是确保共沉淀完全的关键。另外,溶液的浓度、pH值、温度等对共沉淀过程有相当的影响。化学共沉淀法工艺简便,制得粉体性能良好,已广泛应用于多种陶瓷粉体的制备。如ZrO2(Y2O3)等的氧化物陶瓷粉体。选用ZrOCl2·8H2O和YCl3为原料,用NH4OH为沉淀剂,控制适当的共沉淀条件并经一定的后处理可获得颗粒为亚微米级,且具有良好烧结性能的ZrO2(Y2O3)粉体。
