Description

Изобретение относится к области технологии силикатов, а именно к составам глазурей для покрытия изразцов, облицовочной плитки, изделий хозяйственно-бытового назначения.The invention relates to the field of technology of silicates, namely, the compositions of glazes for coating tiles, tiles, household products.

Известна глазурь, содержащая SiO2, B2O3, ZrO2, Na2O, ZnO и другие компоненты [1].Known glaze containing SiO 2 , B 2 O 3 , ZrO 2 , Na 2 O, ZnO and other components [1].

Известна глазурь состава, мас.%: SiO2 36,2-43,0; Al2O3 2,1-8,4; B2O3 28,6-32,3; CaO 4,8-5,0; ZrO2 5,3-8,4; Na2O 5,0-5,3; ZnO 7,4-8,4 [2]. Термостойкость такой глазури 185-190°С, КТР /54-55/×10-7°С-1.Known glaze composition, wt.%: SiO 2 36,2-43,0; Al 2 O 3 2.1-8.4; B 2 O 3 28.6-32.3; CaO 4.8-5.0; ZrO 2 5.3-8.4; Na 2 O 5.0-5.3; ZnO 7.4-8.4 [2]. The temperature resistance of such a glaze is 185-190 ° C, KTP / 54-55 / × 10 -7 ° C -1 .

Цель изобретения - повышение термостойкости и снижение коэффициента термического расширения глазури.The purpose of the invention is to increase heat resistance and reduce the coefficient of thermal expansion of the glaze.

Цель достигается тем, что в состав глазури дополнительно вводят TiO2, при следующем соотношении компонентов, мас.%: SiO2 40,0-45,0; B2O3 28,0-32,0; CaO 4,0-5,0; ZrO2 5,0-8,0; Na2O 0,5-1,5; ZnO 7,5-8,5; TiO2 7,0-8,0.The goal is achieved by the fact that TiO 2 is additionally added to the glaze composition, in the following ratio of components, wt.%: SiO 2 40.0-45.0; B 2 O 3 28.0-32.0; CaO 4.0-5.0; ZrO 2 5.0-8.0; Na 2 O 0.5-1.5; ZnO 7.5-8.5; TiO 2 7.0-8.0.

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

Компоненты сплавляют при 1200°С, расплав гранулируют в воду. Фритту с добавкой 5% глины и электролитов (Na2SiO3) 0,005% размалывают мокрым способом в шаровых мельницах. Полученную суспензию наносят на керамические изделия и обжигают при 1000°С.The components are fused at 1200 ° C, the melt is granulated into water. Frit with the addition of 5% clay and electrolytes (Na 2 SiO 3 ) 0.005% is wet-milled in ball mills. The resulting suspension is applied to ceramic products and fired at 1000 ° C.
