Method for preparing ceramic membrane for separation of condensed component

摘要

A method for preparing a ceramic membrane for the separation of a condensed component which is characterized by comprising the steps of impregnating pores of a ceramic porous material with an alumina sol produced by hydrolyzing an aluminum alcoholate or an aluminum chelate; immersing the ceramic porous material into an aqueous sodium silicate solution; and subjecting the ceramic porous material to a water vapor treatment in a high-temperature water vapor.
