Methods for preparing lead lanthanum zirconate titanate powders with carbonate processes.

摘要

A method for preparing PLZT powder with carbonate process employes Pb(NO3)2, zirconium oxychloride and chlorides of La and Ti as starting materials of which a blended solution consisting is added to another blended solution consisting of NH4OH and (NH4)2CO3 and refluxing at proper condition for a period of time to coprecipitate major particles covered by the carbonates of La, Ti and Pb, and minor particles covered by the hydroxides of La, Ti and Pb of PLZT powder.
