Description

Изобретение относится к технологии силикатов, в частности к составам глазури, которая может быть использована в производстве фарфоровых, фаянсовых и других керамических изделий.The invention relates to the technology of silicates, in particular to glaze compositions, which can be used in the manufacture of porcelain, earthenware and other ceramic products.

Известна глазурь, содержащая SiO2, Al2О3, CaO, К2O, B2О3, SnO2 и другие компоненты [1].Known glaze containing SiO 2 , Al 2 About 3 , CaO, K 2 O, B 2 About 3 , SnO 2 and other components [1].

Известна также глазурь следующего состава, мас.%: SiO2 54,98-56,7; Al2О3 9,4-10,45; Fe2О3 0,05-0,2; CaO 10,0-10,75; MgO 0,01-0,1; Na2O 0,05-0,2; К2О 6,71-7,0; В2O3 10,9-11,3; Cr2О3 0,9-1,3; SnO2 4,5-5,0 [2]. Термостойкость такой глазури составляет 14-15 теплосмен, а блеск 61-65%.Glaze is also known of the following composition, wt.%: SiO 2 54.98-56.7; Al 2 O 3 9.4-10.45; Fe 2 O 3 0.05-0.2; CaO 10.0-10.75; MgO 0.01-0.1; Na 2 O 0.05-0.2; K 2 O 6.71-7.0; B 2 O 3 10.9-11.3; Cr 2 O 3 0.9-1.3; SnO 2 4.5-5.0 [2]. The heat resistance of such a glaze is 14-15 heat exchange, and the gloss of 61-65%.

Наиболее близким аналогом заявленного изобретения является глазурь, включающая, мас.%: SiO2 19-62, Al2О3 5-23, CaO до 6, К2О 0,1-5, В2O3 10-43, SnO2 0,1-13, CdO 2-15, ZrO2 0,1-6. [3].The closest analogue of the claimed invention is glaze, including, wt.%: SiO 2 19-62, Al 2 O 3 5-23, CaO up to 6, K 2 O 0.1-5, 2 O 3 10-43, SnO 2 0.1-13, CdO 2-15, ZrO 2 0.1-6. [3].

Цель изобретения - повышение термостойкости и блеска глазури.The purpose of the invention is to increase the heat resistance and gloss of the glaze.

Цель достигается тем, что в состав глазури дополнительно вводят Sb2О3, при следующем соотношении компонентов, мас.%: SiO2 54,0-56,0; Al2О3 6,0-8,0; CaO 6,4-8,0; К2O 3,0-5,0 В2O3 10,0-12,0; SnO2 4,5-5,5; CdO 4,3-6,0; ZrO2 5,0-6,0; Sb2O3 0,1-0,2.The goal is achieved by the fact that Sb 2 O 3 is additionally added to the glaze composition, in the following ratio of components, wt.%: SiO 2 54.0-56.0; Al 2 O 3 6.0-8.0; CaO 6.4-8.0; K 2 O 3.0-5.0 V 2 O 3 10.0-12.0; SnO 2 4.5-5.5; CdO 4.3-6.0; ZrO 2 5.0-6.0; Sb 2 O 3 0.1-0.2.

Компонент Sb2O3 введен в состав глазури с целью устранения ее физической и химической неоднородности (газовых включений), отрицательно влияющей на термостойкость глазури, ее блеск.The Sb 2 O 3 component is introduced into the glaze in order to eliminate its physical and chemical heterogeneity (gas inclusions), which negatively affects the thermal stability of the glaze and its luster.

Компонент CaO повышает коэффициент преломления глазури, а следовательно, и ее блеск.The CaO component increases the refractive index of the glaze, and hence its gloss.

В таблице приведены составы глазури.The table shows the glaze compositions.

Взвешенные в указанных количествах компоненты сплавляют при 1300°С с последующей грануляцией в воду. Фритту размалывают мокрым способом с добавкой 4-6% глины. Суспензию наносят на изделия и обжигают при 1100°С.The temperature resistance of the glaze will be: for 1 and 2 compositions 20 ± 3 heat exchangers; for 3 composition 25 ± 3. Gloss of glaze will be 75 ± 5% for all formulations. The components weighed in the indicated amounts are fused at 1300 ° C, followed by granulation into water. The frit is ground wet with the addition of 4-6% clay. The suspension is applied to the products and fired at 1100 ° C.
