摘要：

Li2ZnTi3O8 (LZT) microwave dielectric ceramics prepared by reaction-sintering process were investigated. Li2CO3, ZnO and TiO2 powders were mixed, pressed and sintered directly into ceramic pellets without any calcination stage involved. Pure LZT phase was obtained after sintering at temperatures above 1,100 A degrees C for 2 h. LZT ceramic with the maximum bulk density of 3.81 g/cm(3) (96.2 % of the theoretical value) and excellent microwave dielectric properties of E > (r) = 25.8, Q x f = 78,216 GHz and tau (f) = -10.5 ppm/A degrees C was obtained after sintering at 1,100 A degrees C for 2 h. The results show that the reaction-sintering process is a simple and effective method to produce LZT ceramics.
