摘要

The effects of the addition B ₂O ₃ on the sintering behavior, microstructure and microwave dielectric properties of 5Li ₂O-1Nb ₂O ₅-5TiO ₂ (LNT) ceramics have been investigated. With low-level doping Of B ₂O ₃ (≤2 wt%), the LNT ceramics could be fully densified at around 900°C without much degradation in microwave dielectric properties. Similar structures and microwave dielectric properties could be obtained for the densified 1-2 wt% B ₂O ₃-doped ceramics. The 1 wt% B ₂O ₃-doped ceramics sintered at 900°C have better microwave dielectric properties of ε _r = 41.2, Q × f = 9320 GHz (at 4.66 GHz), τ _f = 42 ppm/°C The LNT ceramics could be applied in multilayer microwave devices requiring low sintering temperatures.
