摘要：
The phase evolution and dielectric properties of 10CaO-40ZnO-15B(2)O(3)-35P(2)O(5) (in wt%) glass-ceramics were investigated. Three kinds of crystalline phases including Ca2B2O5, CaZn2(PO4)(2) and Zn-3(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 epsilon(r) = 4.32, Qxf = 16820 GHz (at 13.44 GHz) and tau(f) = -27 ppm/degrees C have been achieved after sintering at 740 degrees 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.
