FIELD: metallurgy. ^ SUBSTANCE: invention relates to receiving of high-porous materials, manufactured of non-metallic inorganic powders, provided for service in the capacity of filters for purifying of gases, solutions, catalyst carriers, heat insulation. From granules of low-melt non-soluted in water organic matter or easy- sublimated matters, or water-soluble organic matters, or ice it is formed simple matrix with the system of correlated open pore. Pores fill non-soluble matrix by running mass, corresponding electricity-conductive or non- electricity-conductive mixture of the powder with polymer or its solution in water or organic vehicle, or astringent composite. Matrix is removed for forming on its place pore system of definite form and size, after removing of matrix material is hardened. ^ EFFECT: method provides ability to receive pours of defined form and size with keeping of strength properties, technology simplification. ^ 10 cl, 31 ex |
