摘要:
There is disclosed a method of fabricating a piezoelectric ceramics. It can obtain a small grain size and a fine grain phase by forming a combined powder being major components, stirring the combined powder with (COOH)2 water solution, dropping a Pb(NO3)2 water solution into the stirred powder, and forming a PZT powder by calcinations and sintering processes.
