Abstract
Abstract The effects of LiF addition on the sinterability and microwave dielectric properties of (Mg 0.95 Zn 0.05 ) 2 (Ti 0.8 Sn 0.2 )O 4 (MZTS) ceramics were investigated. A small amount of LiF addition can effectively lower the sintering temperature of MZTS from 1325 °C to 1150 °C due to the liquid phase effect and induce no apparent degradation of the microwave dielectric properties. With increasing LiF content, the apparent density and dielectric constant decreased gradually, the quality factor increased firstly and then decreased. In particular, MZTS–3.0 wt% LiF ceramics sintered at 1150 °C for 5 h exhibited good microwave dielectric properties of ɛ r = 13.05, Q · f = 119,310 GHz (at 10 GHz) and τ f = −59.2 ppm/°C.
