摘要：

Ba-6-3x(Sm-1-y,R(y))(8+2x)Ti18O54 (R = Nd and La; x 0.6, 0.0 less than or equal to y less than or equal to 1.0) solid solutions in which Nd or La ions are substituted for Sm ions were studied from the point of microwave dielectric materials. In both Sm-Nd and Sm-La series, formation of solid solutions was found, which was deduced from linear change of the lattice parameters. We found high-quality resonator materials in the both series which show high epsilon(r) 84, Q . f products of 9000 GHz, and temperature coefficient of resonance frequency tau(f) 0 ppm/degrees C. The compositions of those materials in the Sm-Nd and the Sm-La series were determined to be y = 0.2 and 0.1, respectively. A relationship between dielectric constant and volume of octahedron is also stated.
