Contrary to most literature, ceramics used in many wireless communication circuits belong to a solid solution series, Ba{sub 6-3x}Ln{sub 8+2x}Ti{sub 18}O{sub 54}, where x depends on the lanthanide (Ln). The condition where temperature coefficient of resonant frequency (Tf) is near zero ppm/{degrees}C is explored from structural and polarizability considerations using Sr{sup 2+}, Pb{sup 2+}, Bi{sup 3+}, and Ln{sup 3+} substitutions. Processing produces preferred orientations in ceramics that are used to estimate very large intrinsic electrical anisotropy.
