Piezoelectric ceramic and manufacturing method therefor

摘要

A piezoelectric ceramic for producing a piezoelectric element having sufficient strength and hardness in spite of compactness is provided. The piezoelectric ceramic contains lead titanate as a primary component and about 0.1 to 5% by weight of tungsten in terms of WO3 relative to the primary component, and about 75% or more of crystal particles constituting the piezoelectric ceramic have particle diameters distributed in the range of about 0.2 mum to 0.8 mum.
