MICROWAVE DIELECTRIC COMPOSITION AND METHOD FOR PRODUCING THE SAME |
摘要 |
A first inventive microwave dielectric composition comprises a ceramic composition represented by AnR4Ti3+nO12+3n, where a is an alkaline earth metal element, R is a rare earth element and characterized in that a case satisfying A = Ba and a case of 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 AXR4Ti3+XO12+3X, 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 (excluding X=1, 2, 4). <??>A variety of small microwave dielectric resonators having excellent transmitting/receiving characters can be mass produced inexpensively from that composition. <IMAGE>
