Abstract Novel temperature stable Li3Mg2NbO6-0.1TiO2 (LMNT) ceramics doped with Li2O-B2O3-Bi2O3-SiO2 (LBBS) glass were synthetized by a solid-state route. The sintering temperature of the LBBS glass doped LMNT ceramics can be effectively lowered to 900 °C. The experimental results revealed that the addition of the LBBS glass can assist to improve the Q × f values while shifting the τf values toward negative direction. Particularly, the 1 wt% of LBBS glass doped LMNT ceramic sintered at 900 °C for 4 h possessed excellent microwave dielectric properties: er = 16, Q × f = 42,648 GHz, τf = −1ppm/°C, which is potential for LTCC applications.

新型温度稳定Li 3 Mg 2 NbO 6 -0.1TiO 2 陶瓷的低温烧结和微波介电性能

摘要 通过固态途径合成了掺杂 Li2O-B2O3-Bi2O3-SiO2 (LBBS) 玻璃的新型温度稳定 Li3Mg2NbO6-0.1TiO2 (LMNT) 陶瓷。LBBS玻璃掺杂LMNT陶瓷的烧结温度可有效降低至900℃。实验结果表明，添加 LBBS 玻璃可以帮助提高 Q × f 值，同时将 τf 值向负方向移动。特别是，在 900 °C 下烧结 4 h 的 1 wt% LBBS 玻璃掺杂 LMNT 陶瓷具有优异的微波介电性能：er = 16，Q × f = 42,648 GHz，τf = -1ppm/°C，这是 LTCC 的潜力应用程序。
