Possibilities of employing cold isostatic pressing in obtaining piezoceramic elements

A possibility to use the method of isostatic pressing when producing piezoceramic elements on the basis of materials of the system lead zirconate-titanate (LZT) has been investigated. It is shown, that the use of the isostatic pressing method permits to obtain piezoceramic elements with a higher complex of electrical and mechanical properties than in the case of monoaxis pressing. The isostatic pressing method permits to manufacture products of complex configurations and large dimensions. No preliminary introduction of organic binding substance to the powder is required during the pressing of LZT system piezoceramics
