Description

Изобретение относится к технологии силикатов, в частности к составам глазурей, которые используются для покрытия керамических изделий, например, в строительстве. The invention relates to the technology of silicates, in particular to the compositions of the glazes that are used to coat ceramic products, for example, in construction.

Известна глазурь, содержащая SiO2, B2O3, Al2O3, ZrO2, CaO, Na2O, MgO, ZnO, Fe2O3 (1).Known glaze containing SiO 2 , B 2 O 3 , Al 2 O 3 , ZrO 2 , CaO, Na 2 O, MgO, ZnO, Fe 2 O 3 (1).

Известна глазурь, содержащая следующие компоненты, мас.%: SiO2 43,56-48,44; Al2O3 9,22-11,76; CaO 12,46-14,45; MgO 2,7-3,33; ZnO 0,66-1,29; Na2O 1,42-2,31; Fe2O3 2,6-3,99; B2O3 18,77-17,48, ZrO2 1,95-3,83; BaO 1,5-2,96; SO3 0,12-0,2 (2).Known glaze containing the following components, wt.%: SiO 2 43.56-48.44; Al 2 O 3 9.22-11.76; CaO 12.46-14.45; MgO 2.7-3.33; ZnO 0.66-1.29; Na 2 O 1.42-2.31; Fe 2 O 3 2.6-3.99; B 2 O 3 18.77-17.48; ZrO 2 1.95-3.83; BaO 1.5-2.96; SO 3 0.12-0.2 (2).

Термостойкость, твердость и блеск глазури в ее известном составе повышены быть не могут. The heat resistance, hardness and gloss of the glaze in its known composition cannot be increased.

Технический результат заключается в повышении термостойкости, твердости и блеска глазури. The technical result is to increase the heat resistance, hardness and gloss of the glaze.

Глазурь получают следующим образом. Glaze is prepared as follows.

Взвешенные в указанных количествах компоненты размалывают, перемешивают и подвергают фриттованию при температуре 1350оС. Расплав фритты гранулируют в холодной воде, после чего осуществляют мокрый помол до влажности 40-50%. По- лученную смесь наносят на керамические изделия и обжигают при температуре 950оС.Weighed amounts of components in said ground, mixed and subjected fritting at 1350 C. The melt granulated frit in cold water, after which the wet milling is carried out to a moisture content of 40-50%. The resulting mixture is applied to ceramic products and fired at a temperature of 950 about C.

Изобретение поясняется конкретными составами. The invention is illustrated by specific compositions.
