| Abstract |
In this study, the microwave dielectric properties of 0-6TiTe_3O_8-0.4MgTiO_3 ceramic with H_3BO_3 and SnO were investigated to reduce the sintering time for the LTCC application. According to the X-ray diffraction patterns, both of 0-6TiTe_3O_8-0.4MgTiO_3 ceramic with H_3BO_3 and SnO had the columbite structure of TiTe_3O_8 Phase, the ilmenite structure of MgTiO_3 phase. The density and dielectric constant of the 0-6TiTe_3O_8-0.4MgTiO_3 ceramics with H_3BO_3 sintered at 830°C for 1 hour were decreased but the quality factor was not changed with addition of H_3BO_3. Also the temperature coefficient of resonant frequency was not changed hardly. In the case of addition of SnO, the density and dielectric constant were increased but the quality factor was decreased and the temperature coefficient of resonant frequency was shifted to the negative(-) direction. |
