Zeolite NaA membranes have been synthesized by secondary growth on the external surface of β£-alumina tubular supports using a semicontinuous system in which fresh gel was periodically supplied to the synthesis vessel. Compared to traditional batch methods, the procedure developed in this work provid
A-type zeolite membranes were prepared on three kinds of substrates with different characters: silicon plate, the surface of which was oxidized; quartz glass plate; and a filter of quartz glass fiber. The membrane syntheses were successfully performed by using the liquid phase separated from the hyd
