摘要：
The effects of BiVO4additions on the microstructure, phases constitute and the microwave dielectric properties of MgTiO3 ceramics were investigated systematically. The sintering temperature of MgTiO3 ceramics with BiVO4 additions can be effectively reduced from 1400°C to 900°C. It was found that the phases BiVO4 and MgTiO3 could be coexisted as observed by XRD. With increasing BiVO4 addition, the sintering temperature was reduced, the bulk density and dielectric constant (εr) gradually increased, the quality factor (Q × f) seriously decreased and the temperature coefficient of resonant frequency (τf) shifted to a negative value. The dielectric properties (εr, Q × f, τf) of MgTiO3 ceramics with w(MgTiO3) = 4% additions sintered at 900°C for 2 h were 18.53, 6832 GHz, -55 × 10-6/°C.
