Stabilities of $Pb(Zr_{0.53}Ti_{0.47})$ $O_3$+x[wt%]C $r_2O_3$ Ceramics and Their Thermal Aging Effects

$Pb(Zr_{0.53}Ti_{0.47})$ $O_3$+x[wt%]C $r_2O_3$ 세라믹스의 공진주파수 온도안정성 및 열에이징 효과

In this paper, Pb(Z $r_{0.53}$ $Ti_{0.47}$) $O_3$+x[wt%]C $r_2$ $O_3$ ceramics were fabricated, and thermal aging effects on the specimen were investigated. After thermal aging, the temperature coefficients of their resonant frequence became stable and only the specimen with C $r_2$ $O_3$ additives in them could have lower temperature coefficientient
