N2 - A new tellurate, BaTiTe3O9, was found in the BaO-TiO2-TeO2 ternary system. Using conventional solid state reaction, the new single phase compound, BaTiTe3O9 phase was synthesized and sintered over the very low temperature range of only 625-700°C. In addition, different calcinations routes, including the effect of TiTe3O8 precursor in the phase formation, were examined. The dielectric properties of BaTiTe3O9 ceramics were determined in the microwave region as well as at low frequencies. The relative dielectric permittivity (εr) and the temperature coefficient of permittivity (TCε) of BaTiTe3O 9 at 1 MHz were measured as 30 and 790 ppm/°C, 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/°C.
