摘要
采用非水基流延法制备了氧化铝陶瓷基片,讨论了非水基流延工艺参数对基片性能的影响。实验结果表明:以甲苯和正丁醇混合液为溶剂,PVB为粘结剂,PEG-400为增塑剂,鱼油为分散剂,当混合溶剂的最佳配比为甲苯:正丁醇为5:3、增塑剂与粘结剂的比值为0.4、粘结剂加入量为5wt%、分散剂加入量为0.6wt%时可获得粘度为2100～3500mPa·s的适合流延的浆料,将流延制得的氧化铝基片生坯在1575℃烧成,密度为3.78g/cm3,介电性能优良。
Alumina ceramic substrates were prepared via non-aqueous tape casting.The influence of non-aqueous tape casting process parameters on the properties of the substrate was disscussed.Experimental results showed that when the mixture of toluene and N-butanol were used as menstruum,PVB as binder,PEG-400 as plasticiser and Fish-Oil was selected as dispersant,and when the optimal ratio of mixed solvent of toluene：N-butanol was 5：3,the ratio of plasticizer and binder was 0.4,the addition of binder was 5wt%,the amount of dispersing agent was 0.6wt%,the preferable slurry with viscosity in the range from 2100 to 3500mPa·s could be gained,which was used in tape casting.The green alumina substrate which gained through casting was sintered at 1575℃.The density of substrate was 3.78g/cm3,and excellent dielectric properties was gained.
