MnO2치환된 PMN계 세라믹스의 유전 및 전기적 특성에 관한 연구

초록

In this study, the dielectric properties of Pb(Mg1/3Nb2/3)O3-PbTiO3 Ceramics have been investigated as a addition of the amount of MnO2(0≤x≤0.9wt%). The Temperature-dependant dielectric characteristics of 0.9PMN-0.1PT relaxor ferroelectric system were improved by enhencinf the extent of the diffuse phase transition(DPT). The maximum dielectric permittivity decreased by substitution MnO2 and the dielectric loss decreased with increasing MnO2 substitution amount. It is sxpected decreasing in inner heat energy for temperature with increasing MnO2 substitution.
