영문 초록

In this study, the (1-x)TiTe3O8-xMgTiO3(x=0.3∼0.7) composition ceramics was investigated to obtain the improved dielectric properties of a high temperature stability and a sintering temperature of less than 900℃ which was necessary for the LTCC. According to the X-ray diffraction patterns of the (1-x)TiTe3O8-xMgTiO3 (x=0.3∼0.7) ceramics, the columbite structure of TiTe3O8 and ilmenite structure of MgTiO3 were coexisted. Increasing the MgTiO3 mole ratio(x), the density and dielectric constant were decreased and temperature coefficient of resonant frequency was moved to the negative direction and the quality factor was increased. In the case of the 0.6TiTe3O8-0.4MgTiO3 ceramics sintered at 830℃ for 3hr, the microwave dielectric properties were εr=29.3, Q×fr=39,600㎓ and τf=+9.3ppm/℃.
