Description
Summary:The fundamental possibility is demonstrated of creating porous permeable ceramic materials with open porosity of not 40, but 60% made of fractionated powders, that makes it possible to increase markedly the productivity of filtering elements and filtration equipment for micro-and ultra-filtration based on them. Ceramic materials may be created from specially synthesized corundum powder whose crystals have the shape of tetragontrioctahedra. The open porosity and the ultimate strength in compression for ceramic materials made from these powders depends on the sizes of the powder particles used, the silica ash particles and forming method used.[PUBLICATION ABSTRACT]
