Ordinary ceramic piezoelectric ceramics

What is the difference between words and ordinary ceramic piezoelectric ceramic is it? 

         The piezoelectric ceramic is designed for an industrial manufacturing ceramic electronic industry, compared with ordinary ceramic products, whether in the chemical composition, microstructure, or have a lot of mechanical and electrical performance differences. 

         Reflect on the most important issues in the electronics industry for the manufacture of a range of aspects of the production of piezoelectric ceramic proposed to reflect the various changes such as piezoelectric ceramics between mechanical properties, heat resistance, high temperature resistance and the number of media occurred. In the application, the amount of dielectric loss constant of the piezoelectric ceramic will decrease the temperature coefficient of capacitance can be adjusted according to actual applications. These features in common with the ceramic body is not, of course, there is no way to adjust.
