摘要：
In this paper, the composites of the TiO2–CaO–MgO–Al2O3–SiO2 glass-ceramic were successfully produced by the method of Sol–Gel from tetrabutyl titanate as the titanium (Ti) source, which were sintering at 1300 °C for 2 h. The dielectric properties of the composites were studied. The highest energy density reached 1.05 J/cm3 with low loss (<0.01), ε = 109 and the breakdown voltage of 48.29 kV/mm, which was 1.38 times higher than that of pure TiO2(0.76 J/cm3).
