Ball Milling Process For Tio Based Varistor

PREPARATION AND CHARACTERIZATION OF TiO –Ta

PREPARATION AND CHARACTERIZATION OF TiO –Ta

3 varistor ceramics were prepared by hot isostatic pressing (HIP) sintering and annealed in different atmospheres. After annealing the microstructure and varistor properties were investigated. EXPERIMENTAL The mixture was ground in a planetary ball mill to obtain the reactants. The purity of each reagent is as follows: TiO 2 (powder, 99.9 %
