Abstract
NanoTiO2/glass composite was potential in pulse power capacitors applications. The glass addition could deduce the porosity, suppress the grain size and improve the BDS of the composite, simultaneously. In this study, the composite was densified successfully by the method of repeating the pre-sintering and ball milling procedure multiple times, which could improve the density and the breakdown strength (BDS) of the composite significantly. When the ratio of TiO2 with 15 % glass addition and the number of pre-sintering times was 4, the energy density achieved the highest energy density 1.41 J/cm3. The method was very simple and inexpensive to compatible with multilayer ceramic capacitor, comparing to sol–gel method and other methods.
