对添加H3 BO3-ZnO-R (BZR)玻璃实现0.4CaTiO3-0.6Ca(Mg13Nb23)O3 (0.6CMNT)介质陶瓷的低温烧结进行了系统的研究.研究结果表明,在一定BZR玻璃添加量(1m％(质量分数)～5m％(质量分数),m是比例系数,且m＞0)的条件下,陶瓷的最佳烧结温度均在950℃;在950℃烧结,BZR玻璃的添加量为2m％(质量分数)时,介电常数εr=47.26976,介电损耗tanδ=0.0098;BZR玻璃的添加量为3m％(质量分数)时,介电常数为εr=47.75029,介电损耗tanδ=0.0102.并且发现,添加适量的BZR玻璃,可以促进晶粒生长,但过量则会在烧结过程中产生过多的液相,且液相扩散严重,致使部分晶粒未能充分生长,而部分晶粒却异常长大,晶粒大小不均匀,影响陶瓷的介电性能.
