MIXTURE FOR PRODUCTION OF POROUS CERAMIC MATERIAL Russian patent published in 2002 - IPC

FIELD: materials technology, particularly, production of porous permeable ceramics for manufacture of ceramic filtering members. SUBSTANCE: mixture contains 60-70 wt.% of fractionated filler in the form of distene sillimanite with rounded form of particles and 30-40 wt.% of finely divided mixture with particles sizing 2-5 mcm, distene sillimanite and 15-20 wt.% of sodium montmorillomite. Cost of produced materials from natural raw materials is lower in 1.5-2 times as compared with that of artificially synthesized materials. EFFECT: higher permeability of ceramic material. 1 tbl
