Title:
分離膜用片端封止型筒状セラミックス基材およびその製造方法
Document Type and Number:
Japanese Patent JP6653004
Kind Code:
B2
Abstract:
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
