(La1?mBim)8+2x(Ti0.95Zr0.05)18O54 (x=2/3) microwave dielectric ceramics prepared by conventional solid-state route were studied. The results show that Bi3+ replaced La3+ into A1 rhombic sites.... The temperature coefficient of resonant frequency (τf) decreases, and the quality factor (Q·f) rapidly decreases. When m=0.05, the optimal microwave dielectric characteristics are achieved as εr=88.63......
