H3BO3와 SnO 첨가에 따른 0.6TiTe3O8-0.4MgTiO3 세라믹스의 마이크로파 유전특성 = Microwave Dielectric Properties of the 0.6TiTe3O8-0.4MgTiO3 Ceramics with H3BO3 and SnO

다국어 초록 (Multilingual Abstract)

In this study, the microwave dielectric properties of 0.6TiTe3O8-0.4MgTiO3 ceramic with H3BO3 and SnO were investigated to reduce the sintering time for the LTCC application. According to the X-ray diffraction patterns, both of 0.6TiTe3O8-0.4MgTiO3 ceramic with H3BO3 and SnO had the columbite structure of TiTe3O8 phase, the ilmenite structure of MgTiO3 phase. The density and dielectric constant of the 0.6TiTe3O8-0.4MgTiO3 ceramics with H3BO3 sintered at 830℃ for 1 hour were decreased but the quality factor was not changed with addition of H3BO3. 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.
