Electrical properties and microstructures of a holmium-doped (Ba_1.01Mg_0.01)O_1.02(Ti_0.98Zr_0.02)O₂ system were studied. Additions of Ho₂O₃ had little effect in preventing the dielectrics from reducing at high temperature, but the resistivity at low temperature increased with increasing amount of Ho₂O₃ when treated in oxidizing atmosphere at the cooling stage. From transmission electron micrograph (TEM) observation, it was noted that the microstructure exhibited a grain core-grain shell structure. Newly developed X7R multilayer ceramic capacitors with Ni electrodes revealed highly reliable electrical properties.
