MICROWAVE DIELECTRIC COMPOSITION AND METHOD FOR PRODUCING THE SAME
摘要
A first inventive microwave dielectric composition comprises a ceramic composition represented by A<sb>n</sb>R<sb>4</sb>Ti<sb>3+n</sb>O<sb>12+3n</sb>, where A is an alkaline earth metal element, R is a rare earth element and characterized in that a case satisfying A=Ba and R=La is excluded and the compositional ratio n=1, 2 or 4. A second inventive microwave dielectric composition comprises a ceramic composition represented by A<sb>x</sb>R<sb>4</sb>Ti<sb>3+x</sb>O<sb>12+3x</sb>, where A is an alkaline earth metal element, R is a rare earth element and characterized in that the compositional ratio X is within a range of 0.5<x<5 (x=1, 2, 4 is excluded). A variety of small microwave dielectric resonators having excellent transmitting/receiving characteristics can be mass produced inexpensively from that composition.
