Title:
METHOD FOR MANUFACTURING PZT-RELATED PIEZOELECTRIC MATERIAL FINE POWDER
Document Type and Number:
Japanese Patent JP2011153061
Kind Code:
A
Abstract:
To obtain a calcined powder of a perovskite single phase of a PZT-related composite piezoelectric material by one calcination which is sinterable at a sufficiently low temperature without using a sintering aid.
The calcined powder of the perovskite single phase sinterable at the sufficiently low temperature without using the sintering aid is obtained by one calcination by previously enough micronizing raw material powder of the PZT-based composite piezoelectric material. As a result, a piezoelectric material having high density and high piezoelectric characteristics is obtained by sintering at a low temperature.
