Abstract
The effects of a glass frit on the sintering and dielectric properties of CaZrO 3 ceramics were investigated. The glass frit, which consists of MnO 2, CaCO 3, MgCO 3, Al 2O 3 and SiO 2, was selected since liquid phase sintering lower the CaZrO 3 sintering temperature. The dielectric properties of CaZrO 3 with glass frit addition are strongly dependent on the densification. CaZrO 3 with glass frit addition can be sintered under 1300 °C (below the nickel's melting point; 1453 °C) and 96% of the theoretical density can be achieved. The dielectric properties at 1MHz are ε r ≈ 27 and a dissipation factor below 0.1%.
