FIELD: metallurgy.
SUBSTANCE: invention relates to powder metallurgy, in particular to the methods of production of high porous cellular materials (HPCM) intended for use as filters, acoustic absorbers, catalyst carriers, heat exchange systems, structural materials working under high temperatures, and can be used in power engineering, machine building, chemical and other industries. The method includes preparation of suspension of the mixture of powders based on chromal, the suspension application to the porous polymer material, the organic substances removal by heating with production of the blank, the blank sintering, at that on the blank after its sintering the chrome oxide Cr2O3 is applied, and secured in volume and on surface of the blank cell by sintering.
EFFECT: increased catalytic reactivity and durability of the material.
