摘要
The effects of H3BO3 additive on the sintering behavior, phase composition, microstructure and microwave dielectric properties of CoZrNb2O8 ceramics were investigated based on the research of pure-phase CoZrNb2O8 (CZN) ceramics. When 2.5 wt% H3BO3 was added to CoZrNb2O8 ceramics, the sintering temperatures significantly decreased from 1250 to 1200 degrees C due to the formation of liquid phase. The ceramic sintered at 1200 degrees C for 4 h exhibited excellent microwave dielectric properties of epsilon(r) = 21.62, Q.f = 40,200 GHz and tau(f) = -16.38 ppm/degrees C. Compared to the results of CZN ceramics, the H3BO3 additives effectively lowered the sintering temperature of CZN ceramics due to the liquid phase effect without detrimental effect on the properties.
