Abstract

PURPOSE: To promote an improvement of piezo-electric characteristic, and a reduction of temperature coefficient for resonance frequency and permittivity throughout a wide range of composition, by means of adding a specific quantity of Pb (Cr1/2Fe1/2)O3 to a ferroelectric piezo-electric porcelain material being composed of PbTiO3 and PbZrO3.
