Reaction Temperature md Electrical Properties of Pb(Mn1/3 Sb2/3) 0.08 Ti0.495 Zr0.425 $O_3$ ceramics by Hydrothermal Synthesis

수열합성에 의한 3성분계 PZT의 반응온도 및 전기적 성질

Reaction temperature md piezoelectric properties of Pb(Mn1/3 Sb2/3)0.08 Ti0.495 Zr0.425 $O_3$ ceramics by hydrothermal synthesis method have been investigated. Sintering density and dielectric constant of sample increased with increasing of hydrothermal reaction temperature, while decreased rapidly above $240^{\circ}C$. Electromechanical coupling factor kp was almost constant at the reaction temperature $160^{\circ}-240^{\circ}C$.
