CERAMIC MIXTURE FOR MAKING FLOOR TILES Russian patent published in 2014 - IPC C04B33/04 

FIELD: chemistry.

SUBSTANCE: invention relates to the technology of silicates and compositions of ceramic mixtures which can be used to make floor tiles. The ceramic mixture for making floor tiles contains the following, wt %: clay 39.0-43.0; pegmatite 26.0-28.0; andesite 10.0-12.0; talc 12.0-14.0; spodumene 7.0-9.0. The components are added in required amounts, separately milled (until passage through sieve 008), mixed and a ceramic mixture with moisture content of 9-13% is prepared, from which a tile is moulded using a semidry method. The tile is fired at temperature of 1250°C.

EFFECT: high water resistance of the tile made from the ceramic mixture.
