Microwave Dielectric Properties of $TiTe_3O_8$ Ceramics with addition at $CaF_2$

$CaF_2$ 첨가에 따른 $TiTe_3O_8$ 세라믹스의 마이크로파 유전특성

The microwave dielectric properties of $TiTe_3O_8-CaF_2$ ceramics were investigated. All sample of $TiTe_3O_8-CaF_2$ ceramics were prepared by the conventional mixed oxide method, and sintered in the temperature of $730^{\circ}C{\sim}750^{\circ}C$. The structural properties of $TiTe_3O_8-CaF_2$ ceramics were investigated by the X-ray diffractor meter. According to the X-ray diffraction patterns of $TiTe_3O_8-CaF_2$ ceramics, the major phase of the cubic $TiTe_3O_8$ were presented. In the case of $1molTiTe_3O_8-0.1molCaF_2$ ceramics sintered at $740^{\circ}C$ for 5hr., the bulk density, dielectric constant, quality factor were $2.8g/cm^3$, 39.1, 36.100GHz, respectively.
