Dielectric material for CaTiO3-La (Mg1 / 2Ti1 / 2) O3-LaA103 microwave

摘要

The present invention relates to a composition comprising CaTiO₃-La (Mg_1/2) O₃-LaAlO₃And more particularly, to a dielectric material for a microwave of the system. The microwave dielectric material of the present invention has a composition represented by the general formula: [(1-x) CaTiO₃-x [(1-y) La (Mg_1/2Ti_1/2) O₃-yLaAlO₃0.3 X 0.6 and 0 Y 1.0 in a composition system represented by the following formula. The dielectric material of the present invention has a dielectric constant of at least 40, a dielectric loss is small, and the temperature coefficient of the resonance frequency has an advantage that it can be easily moved to + and-side with 0ppm /C as the center.
