补充资料:金属有机化合物沉淀
分子式:
CAS号:
性质:按陶瓷化学成分,选择相应的金属有机化合物(盐类)溶液,按给定比例相互混合均匀,然后经一定的处理使其成为粉料的工艺。通常处理方法有两种:(1)水解沉淀。如异丙醇钡Ba(OC3H7)2和叔戊醇钛Ti(OC5H11)4溶解于一定量的异丙醇(C3H7OH)或苯(C6H6)中。在一定温度下回流2h,以确保两种溶液均匀混合。然后在无二氧化碳存在的气氛中剧烈搅拌,慢慢滴入去离子水,使其发生水解反应,析出钛酸钡粉料。(2)脱水沉淀。如将柠檬酸铅、柠檬酸镧、柠檬酸锆和柠檬酸钛的水溶液,按一定比例混合均匀后,用压缩空气喷雾到醇中,用醇吸收溶液中的水分,使柠檬酸盐溶液脱水而成为粉料沉淀出来。过滤后经真空和一定温度加热干燥、焙烧使其分解和合成锆钛酸铅镧粉料。用这种方法可制备高纯度、高活性,化学计量比精确的优质粉料,然而成本高,使用受到限制。
