Description

The invention relates to the glazing of heat-resistant ceramic tiles, stove tiles.

Known slip to obtain a glaze coating, including, parts by weight: frit 100; clay 8-10; zircon 2-4; water 40-45; silica gel 5-10 [1].

The objective of the invention is to obtain a heat-resistant glaze coating on the surface of ceramic products.

The technical result is achieved in that the slip to obtain a glaze coating, including frit, clay, water, silica gel, additionally contains talc and tin oxide in the following ratio, wt.h .: frit 100; clay 4-6; water 40-50; silica gel 3-4; talcum powder 3-4; tin oxide 8-10.

To prepare the frit, use the following components, parts by weight: clay 4-6; silica gel 75-80; talcum powder 6-8; tin oxide 8-10.

For the preparation of a slip, it is most preferable to use clays of Prosyanovsky, Chasovyarsky, Druzhkovsky, Veselovsky deposits.

Table 1 shows the compositions of the slip, and in Table 2 the compositions of the frit.

Table 1 Mixture components Composition, parts by weight: one 2 Frit one hundred one hundred Clay four 6 Water 40 fifty Kremnegel 3 four Talc 3 four Tin oxide 10 8

table 2 Mixture components Composition, parts by weight: one 2 Clay four 6 Kremnegel 75 80 Talc 8 6 Tin oxide 8 10

The components (table 2) are dosed in the required quantities and alloyed at a temperature of 1400-1450 ° C. The melt is granulated into water. The components (Table 1) are loaded into a ball mill and ground to a residue of not more than 2% on mesh No. 0056. The resulting slip is applied to the surface of ceramic products and fired in the temperature range 1000-1150 ° C. Heat resistance of the glaze coating - at least 10 heat shifts.
