A honeycomb shape ceramic porous body, its manufacturing method, and a honeycomb shape ceramic demarcation membrane structure

Japanese Patent JP6023792

B2

An object of the present invention is to provide a honeycomb shaped porous ceramic body in which slit cracks are not easily generated when the porous ceramic body has separation cells which have a separation layer over a disposed intermediate layer and slit cells in which the intermediate layer is not disposed; a manufacturing method for the porous ceramic body; and a honeycomb shaped ceramic separation membrane structure. A separation membrane structure 1 has partition walls 3 including a honeycomb shaped porous ceramic body 9 provided with a large number of pores, and cells 4 to become through channels of a fluid are formed by the partition walls 3. The cells 4 include separation cells 4a and slit cells 4b. In the separation cells 4a, the intermediate layer is disposed on the surface of a substrate 30, and a separation layer is further formed. The intermediate layer has a structure where aggregate particles are bonded to one another by an inorganic bonding material having a thermal expansion coefficient equal to or higher than that of the aggregate particles.
