摘　　要：实验以Ca-Ba-Mg-Al-B-Si-O玻璃和Al2O3粉料为原料,设计玻璃中(Na2O+K2O)含量分别为0、2%、4%、8%的优化玻璃组成,800~950℃低温烧结得到LTCC材料。研究结果表明:随着(Na2O+K2O)含量升高,Ca-Ba-Mg-Al-B-Si-O系玻璃/Al2O3烧结体的体积密度与介电常数逐渐增加,烧结体气孔率随之减小,介电损耗出现先减小后增加的趋势。添加2%(Na2O+K2O)的Ca-Ba-Mg-Al-B-Si-O玻璃/Al2O3材料,在875℃烧结试样显示出优异性能。Use Ca-Ba-Mg-Al-B-Si-O glass andα-Al2O3 powder as raw materials,the optimized glass composition with(Na2O+K2O)content is 0,2%,4%and 8%respectively in the design glass.LTCC materials obtained by low emperature sintering at 800~950℃.The results show that the bulk density and dielectric constant of Ca-Ba-Mg-Al-B-Si-O glass/Al2O3 sinter increase gradually with the increasing of(Na2O+K2O)content.The porosity of sinter decreases accordingly,the dielectric loss decreases first and then increases.The Ca-Ba-Mg-Al-B-Si-O glass/Al2O3 with 2%(Na2O+K2O)addition shows excellent properties at 875℃.
