Microwave dielectric properties of low temperature co-fired glass–ceramic based on B2O3–La2O3–MgO glass with La(Mg0.5Ti0.5)O3 ceramics

Glass–ceramic materials based on B2O3–La2O3–MgO glass with La(Mg0.5Ti0.5)O3 ceramics were fabricated. The sintering behavior and microwave dielectric properties of glass–ceramic were investigated. With the increase of sintering temperature, the εr value of glass–ceramic decreased, while the Q × f value increased obviously and the τf value only increased slightly. Glass–ceramic sintered at 850 °C had an excellent microwave dielectric property: εr = 11.8, Q × f = 14,700 GHz and τf = 7.4 ppm/°C.
