| Abstract: | The Li2MgTi3O8 ceramics were prepared by the conventional solid-state reaction method.The effects of BaCu(B2O5)(BCB for short) addition on sintering behavior and microwave dielectric properties of the Li2MgTi3O8 ceramics were investigated.The results show that BCB addition not only reduces the sintering temperatures of prepared ceramics effectively,but also tunes τf by mixtures of dielectrics closed to zero.When 3%(mass fraction) BCB is added,Li2MgTi3O8 ceramic sintered at 900 ℃ possesses the best microwave dielectric properties: a εr of 27.2,a high Q?f of 48 200 GHz,and a low τf of 0.4×10–6/℃.Moreover,BCB-added Li2MgTi3O8 ceramics possess chemical compatibility with Ag electrodes,which are candidates for LTCC application. |
