Title:
A honeycomb shape ceramic porous body, its manufacturing method, and a honeycomb shape ceramic demarcation membrane structure
Document Type and Number:
Japanese Patent JP6008943
Kind Code:
B2
Abstract:
There are disclosed a honeycomb shaped porous ceramic body to manufacture a honeycomb shaped ceramic separation membrane structure in which a separation performance does not deteriorate under a higher operation pressure than before, a manufacturing method for the porous body, and a honeycomb shaped ceramic separation membrane structure. The honeycomb shaped ceramic separation membrane structure 1 includes a honeycomb shaped substrate 30, an intermediate layer 31, an alumina surface layer 32, and a separation layer 33. The structure has the alumina surface layer 32 on the intermediate layer 31, whereby even when the insides of the cells 4 are pressurized, cracks are not easily generated in a porous body 9 or the separation layer 33 and the deterioration of the separation performance does not easily occur.
