Effect of Glass Additions on Ca[(Li_1/3Nb_2/3)_0.92Zr_0.08]O_3−δ Microwave Ceramics

Abstract:

The effects of ZnO-B2O3-Na2O(ZBN) glass on the sinterability and microwave dielectric properties of Ca[(Li1/3Nb2/3)0.92Zr0.08]O3−δ ceramics were investigated . ZBN glass doping can effectively reduce sintering temperatue by 100~150°C. The temperature coefficient of resonator frequency τf increased with an increase of ZBN glass content and sintering temperatue. When ZBN glass of 1.8wt% were added, the optimum microwave dielectric properties: εr =22.1,Qf =18360GHz and τf = − 9.8×10−6/°C were obtained at the sintering temperature of 1000°C.
