The invention relates to the building materials industry primarily to the compositions of the masses for the production of facing tiles.

Ceramic mass is known for making castings, including the following components, wt%: clay 52; bentonite 3; patron 10; melted glass and pegmatite 32 and. chalk 3 P- 3

The disadvantage of this mass composition is creeping tiles with low density and strength and significant shrinkage.

Closest to the invention is a ceramic mass for the manufacture of tiles 2 3, including the following components: 5 Non-sour clay, 33-40 Clay, basic sintering 20-32, Cleaner 13-20 Melting 13-20 Mel 4-6 significant shrinkage, and relatively low whiteness.

The purpose of the invention is to increase the degree of whiteness and reduce shrinkage of the tiles,

This goal is achieved by the fact that the ceramic mass is mainly for the manufacture of tiles with a high-speed firing mode1 comprising a clay component, a flux. .% g Bilgered component44-59 Plaven24-30 Cleaner1-4 Waste from ammonia soda production 15-23 Waste composition / produced from production ammonia soda sposo6oMj sleduyup№ Y5 wt% CaCO E ZZvTb Si02 Y77.; CaClgl J MaCl 7.5; Ca (OH) d 20.83; SAZOD 8.79; 0.43; MgO 2.2 at sludge moisture

With the introduction of soda mass into the mass of production, discoloration of the ceramic crock occurs. This is due to the occurrence of larnite-type neoplasms, CaMgSi20 diophosphate, etc., also caused by the bleaching action of the chlorine ion contained in the soda production sludge. In addition, the introduction of the sludge into the ceramic mass ensures rapid reactions due to the high dispersion of the sludge and the active form of calcium oxide. This circumstance allows the mass to be burned on high-speed lines. The formation of calcium compounds reduces expansion, increases thermal stability. In addition, obtaining light-colored tiles based on red-hot clays makes it possible to cover them with cheap transparent glazes.

Ceramic tiles are made according to the following technology.

The components in the required ratio are loaded into the mill, the amount of sp. S is 80% of the dry weight. In water, electrolytes sodium tripolyphosphate 0.05% (in excess of 100%) and 0.2% is pre-dissolved. (over 100%) liquid glass. The slip is characterized by a residue on a 2.5% sieve. Press powder with a moisture content of 6% is prepared from the dried slip. Ceramic samples. on a hydraulic press with a specific pressure of 25 Sha. Dry the sample at a residual moisture content and burn it in a laboratory silica oven for 45 minutes at a maximum temperature of Ш80 ° C.

The compositions of the proposed ceramic mass and prototype are presented in table. one"

Properties of the obtained samples are given in table. 2

As can be seen from Table 2, the proposed mass has a low yoef4) thermal expansion sample of 5.1 y; jg- & / degree5 samples have a slight shrinkage up to 2%, sufficient density and strength.

The above examples show the possibility of obtaining a ceramic material with a water absorption of 16-18%, ivory color from a painful glyc.

The use of calcium-containing waste, which is produced in the production of soda by the ammonia method, the sludge production of 3104,787 soda production for building materials is very good. congruent and economically relevant, since the soda industry produces about 100,000 tons / year. sludge contaminating the ground. Returning it to 5 3 .4 production is of great importance to the day of nature conservation. Also, introducing sludge in an amount of 20% into the composition of the mass for ceramic products will reduce the consumption of expensive raw materials mined in quarries. Table
