Microwave Properties of(1-x) Ba3 (VO4) 2-xLi2 MoO4 Microwave Dielectric Ceramics Sintered at Low Temperature
摘要
Abstract
The(1-x) Ba3 ( VO4 ) 2-xLi2 MoO4 ceramics have been prepared by the conventional soli-state reaction method , the effects of different mass ratio of Li 2 MoO4 on the microstructures and microwave dielectric properties of Ba3(VO4)2 are studied.The X-ray diffraction (XRD)test results indicated that Ba3(VO4)2 and Li2MoO4 phase coexist in the composite,and no secondary phases can be detected .The sintering temperature of Ba 3 ( VO4 ) 2 could be reduced with low melting point and negative temperature coefficient Li2 MoO4 .The relative density, dielectric constant and quality factor Q ×f of the compound ceramics all increase firstly and then decrease with the increase of the amount of the Li 2 MoO4 addition , however , the temperature coefficient of resonant frequency τf decreases gradually .The density of the microwave dielectric ceramics with 0.3 Li2 MoO4 addition sintered at 660 ℃ can reach the excellent microwave dielectric properties with εr=11.99,Q ×f=39700 GHz,τf=-24 ppm/℃.关键词
