Study on Ba6-3xSm8+2xTi18O54 Microwave Dielectric Ceramics

摘要：

The effects of different x values on the dielectric properties in the Ba<,6-3x>Sm<,8+2x>Ti<,18>O<,54> microwave dielectric ceramics (0.3≤x≤0.7) were studied. The results showed that the major crystal phase was BaSm<,2>Ti<,4>O<,12> and the sintering temperature of the ceramics was 1340℃ when the x value was 0.67. The dielectric properties were better: ε<,r>≈79, tanδ≈1×10<-4>(1MHz);ε<,r>≈80, Q·f= 9230GHz (3.97GHz), τ<,f>=-17ppm·℃<-1>.
