The rheological properties of corundum suspensions have been investigated. It is shown that for the preparation of corundum slip in the preparation of ceramic highly porous permeable cellular materials (HPCM) by duplicating the structure of polymer matrices, the minimum possible ratio of the dispersed phase and the dispersion medium S: L is 2.3: 1, and the mass content of polyvinyl alcohol in corundum slip is 1 ... 3 & # 37 ;. It has been experimentally established that corundum suspensions with such a ratio of the dispersed phase and the dispersion medium are coagulation structures with a characteristic thixotropic behavior
