Tailoring of the Dielectric Properties of Some Low Sintering Temperature Ceramics

Sylvain Marinel; Sophie d’Astorg; Ahcène Chaouchi

Bearing in mind the attractive dielectrics properties of Ba5Nb4O15, Zn3Nb2O8 and ZnTiO3, we have investigated the lowering of the sintering temperature of these dielectrics using ZnO-B2O3 glass frit addition. The control of the temperature coefficient of the permittivity has been also examined using two different methods. The first method consists in mixing the two oxides ZnTiO3 + TiO2 which exhibit a temperature coefficient with opposite sign. The second method is based on the stacking of two ceramic layers having opposite sign of temperature coefficients. This has been successfully tested in the Ba5Nb4O15 / Zn3Nb2O8 system.
