Abstract

The phase evolution and dielectric properties of 10CaO–40ZnO–15B2O3–35P2O5 (in wt%) glass–ceramics were investigated. Three kinds of crystalline phases including Ca2B2O5, CaZn2(PO4)2 and Zn3(PO4)2 are formed in the sintered glass–ceramics. The dielectric properties change significantly with sintering temperature and phase composition. The optimum microwave dielectric properties of εr = 4.32, Q×f = 16820 GHz (at 13.44 GHz) and τf = − 27 ppm/°C have been achieved after sintering at 740 °C for 2 h. Moreover, the glass–ceramic is chemically compatible with silver (Ag) electrode under the co-fired process. This finding would make the as-prepared glass–ceramic promising candidate for LTCC application.
