3)O3Ceramics (original) (raw)

In this study, the microwave dielectric properties of nano spheroidization glass powders added Ba(Zn 1/3 Ta 2/3)O 3 ceramics prepared by solid state reaction have been investigated. Adding (Ba 0.4 Ca 0.6)SiO 3 nano spheroidization glass powders could effectively promote the densification even in the case of decreasing the sintering temperature. When the glass frit is 0.3 wt% and sintering is carried out at a temperature of 1500 ℃ for 6 hr, a temperature stable microwave dielectric ceramic could be obtained, which has a dielectric constant (ε r) of 30.2, a quality factor (Q×f 0) of 124,000 GHz and a temperature coefficient of resonance frequency (τ f) of 2 ppm/℃.
