摘要
采用KH-550硅烷偶联剂对CABS玻璃/α-Al_2O_3复合粉体表面进行改性,分析了表面改性对流延浆料流变性能的影响,并讨论了微观结构与介电性能的变化。研究结果表明:在添加2%(质量分数)硅烷偶联剂条件下,浆料的分散稳定性得到了明显改善。在烧结过程中偶联剂与玻璃陶瓷形成了钙长石相,并附着在氧化铝的表面。当硅烷偶联剂质量分数为2%时,试样在850℃烧成性能为ρ=3.05 g·cm^(–3),εr=7.89,tanδ=0.1×10^(–3)(1 MHz),主要性能达到LTCC对基板材料的要求。
The surface characteristics of the CABS glass/α-Al_2O_3 glass-ceramic powder were modified by KH-550 silane coupling agent. And the effect of surface modification on the dispersion stability of the rheologic behavior of slurry was analyzed. The result shows that slurry dispersion stability with an addition of 2%（mass fraction） silane coupling agent is distinctively improved. The anorthite phase is formed in the sintering process of coupling agent and composite glass-ceramic, and the anorthite is attached to the surface of alumina. The glass-ceramics（2%-KH-550） sample sintered at 850 ℃ possesses properties： ρ=3.05 g·cm–3, εr=7.89,tanδ=0.1×10–3（1 MHz）,which can meets the requirements of LTCC substrate materials.
