Abstract

This paper presented an innovative method for fabrication of a porous AlO/CaAlO ceramic membrane by combining emulsion method, cement curing and tape-casting technologies. The ceramic membrane featured a smooth surface and a porous internal structure. By adjusting the oil-water volume ratio from 1:1 to 4:1, the porosity of the samples increases from 45.6 to 67.3%, density decreases from 2.07 to 1.32 g/cm and bending strength decreases from 64.3 ± 1.2 to 31.7 ± 0.6 MPa. More significantly, the membranes showed great gas permeability (1.2 × 10-2.3 × 10 Lm h bar), opening up a wide range of applications in the field of gas filtration processes.

摘要

本文提出了一种结合乳液法、水泥固化和流延成型技术制备多孔AlO/CaAlO陶瓷膜的创新方法。该陶瓷膜表面光滑，内部结构多孔。通过将油水体积比从1:1调整到4:1，样品的孔隙率从45.6%增加到67.3%，密度从2.07 g/cm降至1.32 g/cm，抗弯强度从64.3±1.2 MPa降至31.7±0.6 MPa。更显著的是，这些膜表现出很高的透气率（1.2×10 - 2.3×10 Lm h bar），在气体过滤过程领域开辟了广泛的应用。
