COMPOSITION OF CHARGE FOR HIGH-POROSITY CERAMIC MATERIAL WITH LATTICED-CELLULAR STRUCTURE Russian patent published in 2014 - IPC B01J21/00 B01J32/00 B01J35/04 C04B35/00 

FIELD: construction.

SUBSTANCE: composition of a charge for high-porosity ceramic material with latticed-cellular structure for catalyst carriers comprises an inert filler - electrically molten corundum and disperse phase with a strengthening additive. At the same time to increase material strength, they use a high-aluminous porcelain mass as a disperse phase, and the strengthening additive is a composition MgO+SiC, providing for formation of the phase of eutectic composition in the system MgO-SiO₂ when baked in the temperature range of 1250-1300°C with the following ratio of components: electrically molten corundum - 5-20 wt %, high-aluminous porcelain mass - 76.5-90 wt %, strengthening additive MgO+SiC - 3.5-5 wt %.

EFFECT: usage of the specified composition makes it possible to manufacture high-porosity strong ceramic materials with latticed-cellular structure with higher mechanical compression strength with preservation of total volume open porosity.
