On the example of a powder based on mullite, the process of obtaining highly porous ceramic filter materials using porous shells on removable spherical carriers was tested, including the deposition of thin shell coatings from powder based on mullite on spherical granules of expanded polystyrene, pressing the mixture in the form of evenly distributed in the powder of the same composition ( matrix) and sintering. It’s shown that the resulting material is characterized by a good complex of filtering properties and a developed biporous structure.
