The optimum synthesis condition of PZT nanopowder was determined through characterizing effect of 4 calcination temperatures on its particle size distribution,crystal structure, microstructure, and piezoelectric properties of PZT ceramics. The PZT/chrysotile fiber/cement composites (PZTCC) were prepared combining with the ultrasonic dispersing technology,and the cystal structures of the mixed powder and the piezoelectric properties of the PZTCC wafer after pressing & polarization were measured, respectively.The results show that PZT has the best perovskite cystal structure and plump crystalline grain at the calcinated temperature of 800 ℃,and the corresponding PZT ceramic,PZTCC wafer have relatively high piezoelectric coefficient d33 of 119.2 pC/N, 32.5 pC/N respectively.
