ONE-END SEALED TYPE CYLINDRICAL CERAMIC SUBSTRATE FOR SEPARATION MEMBRANE, AND MANUFACTURING METHOD OF THE SAME
To provide a one-end sealed type cylindrical ceramic substrate for a separation membrane which suppresses deterioration in separation performance of a separation membrane filter.SOLUTION: With a one-end sealed type cylindrical ceramic substrate 10 for a separation membrane, a dense glass layer 18 is formed on an outside surface of a sealing part 14 which is anchored on one-side opening of a cylindrical part 12 of a porous ceramic substrate 16 to seal the opening and in which a projection 20 having a fracture surface having a surface structure different from that of the cylindrical part 12 is formed. This configuration enables a defect-free uniform separation membrane to be formed on a surface of the one-end sealed type cylindrical ceramic substrate 10 for the separation membrane, thereby suppressing significant deterioration in separation performance of the separation membrane due to generation of local leaks or the like.SELECTED DRAWING: Figure 2
【課題】分離膜フィルターの分離性能の劣化を抑制する分離膜用片端封止型筒状セラミックス基材を提供する。【解決手段】分離膜用片端封止型筒状セラミックス基材１０によれば、多孔質セラミック基材１６の円筒部１２の片側の開口に固着されて開口を封止し、円筒部１２に対して表面構造が異なる破断面を有する突起２０が形成された封止部１４の外側表面に緻密なガラス層１８が形成されている。このため、分離膜用片端封止型筒状セラミックス基材１０の表面に欠陥のない均一な分離膜を形成することが可能となり、局部的な分離膜のリークなどの発生による分離膜フィルターの著しい分離性能の劣化を抑制することが可能となる。【選択図】図２
