FIELD: chemistry.
SUBSTANCE: ceramic mixture for making facade tiles includes, wt %: kaolin 72.5-73.0; bentonite 2.0-2.5; phosphorite 6.0-7.5; zircon 14.0-16.0; mullite 3.0-3.5. The mixture has frost resistance of 100 cycles. The articles are dried to moisture content of 1-6% and fired at 1260-1280°C. Colour glaze is then applied (spraying, wetting) on the surface of the articles and the articles are fired for the second time at 950-1000°C.
EFFECT: high frost resistance of facade tiles made from the ceramic mixture.
