The dielectric ceramics comprised of (Zn1-xMgx)TiO3 (x=0.1~0.5, abbreviated to ZMT) were developed by conventional mixed-oxide method combined with a semi-chemical processing. V2O5 was used as sintering aids to lower the sintering temperature of ceramics. The results showed that the hexagonal phase stability region extended from 900 to 1150°C as the amount of magnesium increased. The densification temperature of ZMT ceramics could be reduced from 1200 to 875°C by V2O5 additions and using semi-chemical processing, the relative density of ZMT ceramics with 1.00wt% V2O5 addition reach 95% at 875°C. The dielectric properties of ZMT were measured at different frequencies and the results showed that there existed a decreasing tendency of the loss tangents (tg δ) with increasing measuring frequency. It is concluded that εr=22 and tg δ= 5.7×10-4 can be obtained for ZMT ceramics at sintering temperature 875°C.
