PREPARATION AND CHARACTERIZATION OF TiO₂-Ta₂O₅-CaCO₃ VARISTOR CERAMICS BY HOT ISOSTATIC PRESSING (HIP) AND POST-ANNEALING

TiO₂-Ta₂O₅-CaCO₃ varistor ceramics were prepared by hot isostatic pressing (HIP) and annealed in oxygen and nitrogen, respectively. The nonlinear coefficient α, the breakdown voltage EB and the leakage current JL of samples were tested using a varistor dc parameter meter. The average barrier height...
