化学共沉淀法制粉化学共沉淀法制粉preparation of powder by chemical coprecipitation method 化学共沉淀法制粉preparation of powder byehemieal eopreeipitation method用一种或多种金属盐溶液，通过化学反应形成沉淀物，然后经过脱除溶剂和加热分解而制得陶瓷粉体的方法。由这种方法制得的粉体均匀性好，其中所包含的正离子能在原子大小水平上混合在一起，反应性能好，易于烧结。 化学共沉淀制粉的工艺原理是:将沉淀剂加入溶液中，发生下列反应 A++B-一 AB土当溶液中A十与B一离子浓度的乘积〔A十〕·〔B一〕大于其溶度积S协B时，溶液即呈过饱和而AB化合物发生沉淀。在实际反应中，沉淀过程是很复杂的，常常需要调节溶液的酸度、反应温度、沉淀剂的浓度及其加入速度等来扛制沉淀反应速度和沉淀是否完全。当溶液中存在有多种能与沉淀剂发生反应的离子时，生成物中溶度积最小的化合物首先产生沉淀，随着沉淀剂的继续加入和浓度的增加，较大溶度积的化合物会依次被沉淀下来。为使沉淀反应完全，往往使用过量的沉淀剂，以增大离子的浓度乘积。这样在阳离子的种类、大小相似时，就更易于产生共晶物质而共同沉淀出来。这种方法对在某些基体中掺入微量活性离子尤为方便。 化学共沉淀方法可分为:①直接用过量沉淀剂使络液中全部阳离子同时沉淀下来成为混合物;②通过特定沉淀剂，使阳离子形成符合化学计量比要求的前驱体化合物。例如BaTIO(CZO4):·4 HZO(Ba与 Ti比为1:1)沉淀即属此情况;③为避免沉淀剂局部过浓，沉淀剂可通过化学反应在溶液中逐步生成，从而产生均相沉淀。例如把尿素溶解到反应液中，通过加热到70℃以上，使尿素水解产生氨CO(NHZ)2+3 HZO垫2 NH。·HZO+COZ氨在溶液内一旦生成，即与金属离子反应生成沉淀，这样发生的氮浓度低、均匀，获得的粉体纯度高，粒径大小和形状均齐性好。 共沉淀法的适用范围广，除可用于制备各种难溶的金属氢氧化物和氧化物外，还可用于制备碳酸盐、草酸盐、硫酸盐和磷酸盐等。但是如果两种反应物在水中溶解度相差过大，或反应物不是以相同的速度沉淀时，或生成物形成稳定的过饱和溶液时，化学共沉淀法即不宜使用。(袁启华)
