Abstract
PURPOSE: To make uniform the characteristics of the upper, lower and central portion of a sheet put one step by coating a powder containing a piezoelectric ceramic wiht a same quality on the surface of the upper and lower setter composed of ZnO2, MgO and Al2O3 used for an weight in performing burning of the piezoelectric sheet.
CONSTITUTION: A piezoelectric sheet 3 is made by cutting or stamping out asheet in accordance with a desirable shape, and it is acconmodated in a burning furnace through a sheeting powder 2 for reaction preventionus. Thereafter, the burning is performed by tightening the upper and lower portions of the sheet 3 with an upper and lower setter 4 of ZnO2, MgO and Al2O3, at this time the surface of the setter 4 is covered with a coating burn layer of a powder containing a piezoelectric ceramic with a same quality. According to such a process, the vaporation of Pb) in the sheet 3 can be prevented, and the characteristics of the upper, lower and center of the sheet 3 put in a step lamination are uniformed to improve a yield.
