AB2O4型尖晶石结构微波介质陶瓷研究进展
Research progress on AB2O4-type spinel microwave dielectric ceramics
摘要
Abstract
AnB2nO4n (n = 1, 2, 3) spinel ceramics are good microwave dielectric materials with high quality factor, tunable permittivity and temperature coefficient of resonance frequency, and chemical compatibility with silver, which makes them potential candidates for low temperature co-fired ceramic (LTCC) application. The crystal structure of spinel ceramics is introduced and the microwave dielectric properties of spinel ceramics with different n values are summarized. The evolution of cation distributions is discussed as Li element is introduced into the spinel lattice, and it is focused on the sintering temperature (S.T.) and microwave dielectric properties of Li-based spinel ceramics and their properties adjustment by the ion substitution. Furthermore, the components of some candidates are modified to achieve better combination of microwave dielectric properties. The specific methods include formation of solid solution and second phase, and non-stoichiometric adjustment. In the end, the possibility of Li-based spinel ceramics is evaluated for practical application.关键词
