The low temperature sintering of (Zn0.9Mg0.1)TiO3 was studied by conventional solidstate reaction methods,adopting Mg substitute a part of Zn to form an ilmenite type infinite solid solution (Zn0.9Mg0.1)TiO3.The low melting point glass ZnOB2O3SiO2(ZBS) significantly increased the density of (Zn0.9Mg0.1)TiO3 ceramics,and the sintering temperature was lowered to 900 ℃. Single (Zn0.9Mg0.1)TiO3 phase ceramics was obtained, which had excellent microwave dielectric properties. By adding 0.5% ZBS glass,the ceramics could be well sintered at 900 ℃,the microwave dielectric properties were described as follows:εr=20.53，Q×f=61 630 GHz(f=7.4 GHz).
