Method of manufacturing piezoelectric ceramic device

Preparing the main component of the piezoelectric ceramic green sheet is a composition of lead oxide green. Preparing a conductive paste containing a major component of the piezoelectric ceramic composition and a metal and a refractory oxide of Ag. On the green sheet partially coated conductive paste. Coated with a conductive paste contained in the green sheet at a temperature of the melting point of the oxide and sintering the calcined piezoelectric ceramic produced below the conductive paste. Obtained by the method of the piezoelectric ceramic green sheet during firing no deformation or cracks.
