Improvement of the Technology of High-Porosity, Permeable, Cellular, Ceramic Materials

Abstract

The rheological properties of corundum suspensions were studied. It is shown that to prepare corundum slurry in obtaining ceramic, high-porosity, permeable, cellular materials (HPCM) by the method of duplicating the structure of polymer matrices the minimum possible ratio S : L of the disperse phase and the dispersion medium is 2.3 : 1 and the weight content of polyvinyl alcohol in the corundum slurry is 1 – 3%. It was proved experimentally that corundum suspensions with such a ratio of the disperse phase and the dispersion medium are coagulation structures with characteristic thixotropic behavior.
