Description

The invention relates to the composition of the slip used for glazing 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, zircon, water, additionally contains quartz pegmatite and bone ash in the following ratio of components, parts by weight: frit 100; clay 2.5-3.5; zircon 2.5-3.5; water 40-50; quartz 2.5-3.5; pegmatitis 6.0-9.0; bone ash 6.0-9.0.

To prepare the frit, the following components are used, weight parts: zircon 12-16; pegmatitis 12-16; quartz 30-35; glass container fight 38-41.

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 2.5 one hundred Zircon 2.5 3,5 Water 40 fifty Quartz 3,5 2.5 Pegmatite 6 9 Bone ash 9 6

table 2 Mixture components Composition, parts by weight: one 2 Zircon 12 16 Pegmatite 12 16 Quartz 35 thirty Glass Fight 41 38

The components (table 2) are dosed in the required quantities and alloyed at a temperature of 1430-1450 ° C. The melt is granulated into water. The components (Table 1) are loaded into ball mills 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 1100-1200 ° C. Heat resistance of the glaze coating - at least 12 heat shifts.
