Influence of ZnO-B₂O₃-Na₂O Glass on Microwave Dielectric Properties of Ca[(Li_1/3Nb_2/3)_0.8Sn_0.2]O_3−δ−0.1TiO₂ Ceramics

Abstract:

The effects of ZnO-B2O3-Na2O(ZBN) glass on the sinterability and microwave dielectric properties of Ca[(Li1/3Nb2/3)0.8Sn0.2]O3−δ−0.1TiO2 (CLNS−0.1TiO2) 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 3wt% were added, the optimum microwave dielectric properties: εr =28.8,Qf =10960GHz and τf = − 7.5×10−6/°C were obtained at the sintering temperature of 1050°C.
