摘要

A method is described for preparing an electrically conducting composition for the purpose of metallizing unfired piezoceramic material, including the preparation of a paste based on silver, characterized by the fact that in order to prevent the burning-out of the silver in the firing of the piezoceramic articles and to produce high-grade multilayer piezoceramic articles, 50 to 80% by weight of the paste is mixed with 20 to 50% by weight of the piezoceramic powder, the mixture is heated to 900 to 910 exp 0 C, the resulting cake (sinter) is ground, and 10 to 30% by weight of it is mixed with 70 to 90% by weight of silver powder.
