Abstract :
The method of ultrasonic (US) compaction for the fabrication of Pb(ZrTi)O3 PZT piezoceramics was approved. The values of density, granularity, shrinkage of ceramic samples, sintered from the compacts compacted by traditional uniaxial pressing and by ultrasound action are compared. It is shown that US compaction contributes to sintering temperature lowering and to PZT piezoceramics granularity reduction
