Preparation and Properties of ZnTiNb2O8 Microwave Dielectric Cramics
The single phase of ZnTiNb2O8 ceramics was obtained at 1050 °C via traditional solid-state method. The formation of the ZnTiNb2O8 phase in the calcined powders has been investigated as a function of calcination conditions by XRD technique. Morphology and particle sizes have been determined via SEM technique. The microwave dielectric ceramics ZnTiNb2O8 which sintered at 1150°C exibit the best microwave properties: high permittivity (εr =34.2), high quality factor (Q*f = 28696 GHz), but very negative temperature coefficient of resonant frequency (τf = -75.841ppm/°C).
