本文重点研究了凝胶注模法制备多孔莫来石陶瓷的过程中固含量、表面活性剂量、搅拌速度等参数对多孔陶瓷显微结构的影响.结果表明,多孔陶瓷的气孔率、孔径尺寸和连通性可以通过控制制备过程参数来进行调节.当固含量从40wt%增加到70wt%,样品的开孔率和总气孔率分别从88.49%和91.27%降低到76.94%和83.04%,而密度从0.276 g·cm-3增加到0.536 g· cm-3.当表面活性剂浓度由0.25wt%增加到lwt%时,样品开孔率基本保持不变,总气孔率先由84.34%增加到93.26%,再减小到87.63%;密度则由0.413 g·cm-3减小到0.378 g· cm-3,再增加到0.391 g·cm-3.当搅拌速度由1000 r/min增加到1800 r/min时,开孔率由78.12%减小到72.85%,总气孔率则由79.95%先增加至84.18%,再减小到77.09%.
