| Abstract: | Ph(Ni1/3Nb2/3)O3-based diphasic ceramic meeting X7R temperature stable dielectric require was prepared by PbTIO3 particle coating method. Morphologies of uncoated and coated particles were observed by TEM. The results showed that PT was coated on the surface of particles. The solution reaction between two phases could be supressed by PT coating. The temperature dependence of capacitance can be improved with composite structure. The function of PT coating was analized. |
