METHOD OF MANUFACTURING STRUCTURAL, HEAT INSULATING CERAMICS AND COMPOSITION FOR MANUFACTURING THEREOF Russian patent published in 2010 - IPC C04B35/16 C04B35/626 

FIELD: building.

SUBSTANCE: method involves preparation of a bulk that is a mineral binding additive - zeolite rock, implying drying thereof at temperature 110-150°C and crushing to the size 0.5 mm and less, slip-process preparation of a fluidising agent by the combined wet ground of said zeolite rock to sieve residue 0088 no more than 2-3% in a ball grinder with adding calcium lignosulphonate (sulphite waste liquor) to produce zeolite-lignosulphonate slurry of density 1.20-1.25 g/cm³, plasticisation of cindery microspheres with the prepared slurry, mixing of a dry binding additive with plasticised microspheres, dry pressing of the products under pressure 20-25 MPa and baking of the half-finished product at temperature 980±20°C. The composition for manufacturing the ceramic material contains the components in the ratio, wt %: cindery microspheres 60-95, zeolite rock 5-40 wt %, zeolite-lignosulphonate slurry 12-16 over 100 %.

EFFECT: lower heat conductivity of pottery with maintaining high durability thereof.
