A method of producing an inorganic membrane consists of depositing a membrane precursor on a porous carrier, followed by thermal treatment. Characterized in that, at least two intermediate layers are deposited between the carrier and the membrane. The layers consist of aluminium oxide from aluminium hydroxide sol, which may contain an admixture of a binder. Each deposited layer is subjected to thermal treatment, i.e. drying at the temperature of up to 383 K and calcination at the temperature of up to 1200 K. Then, the membrane is produced. |
