A New Modified PbTiO_3 Piezoelectric Ceramic Material
Source abstract
Abstract
A new modified PbTiO_3 piezoelectric ceramic material added with Pb(Mn1/3Sn2/3)O3 , CaCO3,Bi2O3, NiO was prepared. The modified material has high piezeoelectric activities, large piezoelectric anisotropy as well as low dielectric constant, and low mechanical quality factors. The typical composition of this material obtained from experiments is Pb0.80Ca0.20[(Mn1/3Sb2/3)0.05Ti0.95]O3+0.5wt% NiO+1wt%Bi2O3. Under the optimized preparation technique, its main performance are as follows.
