文档介绍:第 卷 第 期 硅 酸 盐 通 报
40 3 has attracted much attention due to its low sintering temperature and good microwave
dielectric property, which is expected to be one of the candidate materials for low temperature co-fired ceramics (LTCC).

This article mainly introduces several preparation methods of Li2 ZnTi3 O8 ceramics and its advantages and disadvantages.
The effects of ion replacement modification, oxide doping modification and low-temperature co-firing on the overall dielectric

properties of microwave dielectric ceramics are also analyzed. The research and application of Li2 ZnTi3 O8 microwave
dielectric ceramics in the next stage are prospected.
Key words:
