| Abstract: | 0.4CaTiO3-0.6(Li1/2Nd1/2)TiO3(CLNT) microwave dielectric ceramics were prepared by conventional solid reaction method.The effects of BaCu(B2O5)(BCB) and 2ZnO-B2O3(ZB)glass composite sintering additive on sintering behavior,phase composition,micromorphology and dielectric properties of CLNT ceramics were investigated.The results show that the sintering temperature of CLNT ceramics is effectively lowered from 1 300 ℃ to 925 ℃ by adding 3%(mass fraction) ZB and 5%BCB.With the addition of BCB,the relative permittivity(εr) increase first and then decrease,the dielectric loss decrease and then reach saturation,and the temperature coefficient of resonant frequency decrease.The CLNT ceramics doped with 3% ZB glass and 5% BCB sintered at 925 ℃ for 2 h show the optimum dielectric properties: εr=83.2,tanδ= 0.013 and τf=35.7×10–6/℃,which meets the requirements of the high permittivity materials for multilayer microwave components. |
