Description

The invention relates to the technology of silicates and can be used in the manufacture of ceramic glazed tiles mainly dp floors and exterior cladding of buildings.

The purpose of the invention is to increase frost resistance and wear resistance, cost reduction while maintaining heat resistance.

The compositions of the proposed glaze are presented in table. one,

The properties of the glaze are presented in table. 2

Perlite, zircon concentrate, zinc oxide, clay, kaolin, datolite concentrate and pre-fused flux are used to obtain the glaze.

The flux is prepared by fusing at 1350 ° C and subsequent granulation of such raw materials as sand, chalk, barium carbonate, zircon concentrate, boric acid, borax, zinc oxide, and alumina. It has the following oxide composition, wt.X:, 06; 8.78; CaO 11.48; MgO 3.06; 19.15; ZrOi 6.56; ZnO 1.84; You 4.13.

The glaze is prepared as follows.

in a way.

In accordance with the oxide composition, grinding components are loaded into ball mills. The preliminary melting of the flux is carried out for 3.5 hours in an electric silica oven. When grinding as a diluent additive vvo4 CO
