Sintering Time Influences on Microstructure and Electrical Properties of Scandium Doped Zinc Oxide Varistor Ceramics

摘要：

　　Sc2O3-doped zinc oxide varistor ceramics were prepared by a solid reaction route.The microstructure and the electrical properties was analyzed by scanning electron microscope and X-ray diffraction.Sintering time influences on the microstructure and the electrical properties of Sc2O3-doped zinc oxide varistor ceramics are studied.The results show that the electrical properties of Sc2O3-doped zinc oxide varistor ceramics sintered at 1000 ℃ and sintered for 1 h was better: the voltage gradient was 653 V/mm;the leakage current was 0.18 μA and the nonlinear coefficient was 57.1.
