FIELD: process engineering. ^ SUBSTANCE: invention relates to process engineering and can be used for producing high-porosity materials made from non-metal inorganic powder suitable in operation as filters of gas, solvents, catalyst carriers and heat insulation agents. In compliance with this method, porous matrix with a system of intercommunicated open pores is produced from granules of low-melting water-insoluble, or readily-sublimated or water-soluble organic substances, or ice. Pores are filled with fluid mass that does not dissolve aforesaid matrix and represents conducting or not-conducting mix of polymers, mix of polymer powder with polymer binder, suspension or polymer solution with water or organic fluid. Matrix is removed to produce preset shape- and size-pores in its place. Matrix removed, obtained material is consolidated. ^ EFFECT: production of preset shape- and size pores, simplified process. ^ 6 cl, 16 ex |
