  • 摘要: 以α-Al2O3为骨料，羧甲基纤维素作为成孔剂，高岭土、TiO2作为高温粘结剂和烧结助剂，采用干压成型工艺和固态粒子烧结法制备出了圆板型多孔α-Al2O3陶瓷膜支撑体（?=50 mm，厚度为2 mm）。研究了成孔剂用量、高温粘结剂和烧结助剂的用量、烧结温度因素对支撑体性能的影响。结果表明，制得的支撑体孔隙率在34%以上，孔径在2.23 ~6.75 μm，耐酸碱度在98%以上，机械强度高。
    Abstract: Circular plate-shaped porous ceramic membrane support(diameter of 50 mm，thickness of 2 mm)， with alumina as aggregate， carboxymethylcellulose as pore-fomring agent， kaolin and titanium dioxide as high temperature binder and sintering additive， was prepared by dry-pressing and solid sintering. The effects of the amount of pore-fomring agent，high temperature binder，sintering additive and sintering temperature on the properties of support were studied. The results indicate that support with porosity beyond 34%，pore size between 2.23 and 6.75 μm，acid/ alkali resistance beyond 98% and high mechanical strength was prepared.
