CuBi2(V2O5)(CBV for short) doped Li2O-ZnO-TiO2 system ceramics were prepared by the conventional solid-state reaction, using CuBi 2 (V 2 O 5 ) as sintering additive, which was common low melting point oxide. The behavior of sintering, phase composition, microstrceture and microwave dielectric properties of Li2O-ZnO-TiO2 system ceramics were characterized or measured by means of XRD and SEM. The results show that, the ceramic doped with 3.25%(mass fraction) CBV sintered at 875℃shows good microwave dielectric properties:εr=25.63,Q·f=53 400 GHz,τf=–5.27×10–6/℃.
