摘要
In this experiment, in order to prepare high quality inorganic membranes which are conventionally not tough enough to bear high pressure, we tried three kinds of CaO-MgO-SiO2 adhesives. It was found that unlike conventional adhesives used for porous supporters, these three kinds of adhesives had high mechanical strength, which ensured the good properties of the membranes with high porosity. Adhesive, sintering temperature, pore-forming material and holding-heat time were taken into account. The relationships between the properties of membranes and the four factors were found out through a kind of orthogonal experiment named L9(34). Then we got a better way to prepare Al2O3 membranes which could have a porosity of over 45% and even remain the strength of over 40 MPa.
