• A new tellurate, BaTiTe_3O_9, was found in the BaO-TiO_2-TeO_2 ternary system. Using conventional solid state reaction, the new single phase compound, BaTiTe_3O_9 phase was synthesized and sintered over the very low temperature range of only 625-700℃. In addition, different calcinations routes, including the effect of TiTe_3O_8 precursor in the phase formation, were examined. The dielectric properties of BaTiTe_3O_9 ceramics were determined in the microwave region as well as at low frequencies. The relative dielectric permittivity (ε_r) and the temperature coefficient of permittivity (TCε) of BaTiTe_3O_9 at 1 MHz were measured as 30 and 790 ppm/℃, respectively. The dielectric properties were maintained up to microwave region without degradation. The dielectric permittivity and Q×f product obtained were 29 and 1, 700 GHz at 7.6 GHz, respectively. The temperature coefficient of resonance frequency (TCF) showed a large negative value of -372 ppm/℃.
