摘　　要：实验设计Ca-Ba-Mg-Al-B-Si-O玻璃分别与Al2O3、TiO2、ZrO2、SiO2复合,通过调控Ca-Ba-Mg-Al-B-Si-O玻璃/氧化物组成,低温烧结制备玻璃复合氧化物材料,重点研究了玻璃/氧化物材料的烧结性能与介电性能。研究结果表明,氧化物种类对Ca-Ba-Mg-Al-B-Si-O玻璃/氧化物材料的烧结性能、热性能、介电性能有较大影响,Al2O3有利于促进玻璃/氧化物材料烧结致密,SiO2可以用于降低该体系介电陶瓷材料的介电常数。Ca-Ba-Mg-Al-B-Si-O玻璃/Al2O3材料于875℃烧结试样的综合性能最好,其体积密度为3.10 g.cm^-3,10 MHz下介电常数为8.03,介电损耗为0.0005,基本可以达到LTCC材料的使用要求。Glass/oxide composites,consisting of Ca-Ba-Mg-Al-B-Si-O glass and various oxides(Al2O3,TiO2,ZrO2 and SiO2),were prepared by using a low-temperature sintering method.The property-composition relationship of the Ca-Ba-Mg-Al-B-Si-O glass/oxide was studied,in terms of sintering behavior and dielectric properties.It was demonstrated that different oxides had different effects on sintering,thermal and dielectric properties of Ca-Ba-Mg-Al-B-Si-O glass/oxide composites.The presence of Al2O3 promoted densification of glass/oxide composites,while the addition of SiO2 reduced dielectric constant of the ceramics.Specifically,the Ca-Ba-Mg-Al-B-Si-O glass/Al2O3 sample sintered at 875℃exhibited a bulk density of 3.10 g·cm^-3,a dielectric constant of 8.03 at 10 MHz,a dielectric loss of 0.0005,making it potential candidate for low-temperature co-fired ceramics.
