초록

Tw types of Pb(Mn$\sub$1/3/Nb$\sub$2/3/)O$_3$+PZT Ceramics had been fabricated by hot-pressing method. One had cause grain and the other had fine grain doe to Cr$_2$O$_3$ addition. These specimen were poled by applying the DC electric field in various steps. The effects of thermal aging on their piezoelectric characteristics and temperature stability of the frequency were investigated.
