54) ГЛУШЕНАЯ ГЛАЗУРЬ ДЛЯ : МЕТЛА ескОЙ ПЛИТКИ54) MUTTED EYE FOR: BROOMED TEXT TILES
Изобретение относитс к составам глазурей дл керамических изделий. Известна глазурь 1, включающа вес.%: SiOa40-55 8-18 15-30 2-4 4-7 :1-3 0,1-9,0 0,1-9,0 и, кроме того, по крайней мере один окисел из группы , Li.jO, MgO, Cu COgOg, WOg, MoOg 0,1-2. Известна также глазурь 2, соде жаща , вес.%: SiOg51,46-52,24 7,82-7,94 0,48-0,4 TiOa0,13-0,14 CaO7,23-7,33 MgO1,37-1,39 0,74-0,75 1,82-3,97 17,06-17,3 Zr02 5 -11,89 Температура обжига 940-1140C, термический- коэффициент линейного р ширени (ТКЛР) 5,26 10гpaд Указанные гла.зури имеют повышенную температуру обжига и обладают недостаточно высоким ТКЛР. Целью изобретени вл етс снижение температуры обжига и повышение ТКЛР. Указанна цель достигаетс тем, что глазурь, включающа SiO , AlgO, ZrO, , Na2O, CaO, содержит указанные компоненты в следующих количествах , вес.%: SiO2.33,0-40,0 ,5-11,5 ZrOa13,2-18,0 В Оз18,5-22,5 ,0-6,0 СаО11,0-15,0 Глазурь готов т по обычной техноогии . Варку фритты ведут при 13001350с в течение 3-4 ч. Фритту грануируют в воде и мокрым помолом в шаовых мельницах изготавливают шликер, оторый нанос т на поверхность издеий . Температура обжига глазури 920- 80°С. В таблице приведены состав глазури ее свойства. Состав глазури, вес.% SiOjL А12.Оз Температура варки, С 1300-1350 Температура наплавлени , с 920-980 This invention relates to glaze compositions for ceramic products. Known glaze 1, including wt.%: SiOa40-55 8-18 15-30 2-4 4-7: 1-3 0.1-9.0 0.1-9.0 and, moreover, at least one oxide from the group, Li.jO, MgO, Cu COgOg, WOg, MoOg 0.1-2. Also known is the glaze 2, containing, wt.%: SiOg51.46-52.24 7.82-7.94 0.48-0.4 TiOa0.13-0.14 CaO7.23-7.33 MgO1.37 -1.39 0.74-0.75 1.82-3.97 17.06-17.3 Zr02 5 -11.89 Firing temperature 940-1140C, thermal-coefficient of linear p of width (TCLE) 5.26 10g. These glazuri have a high firing temperature and have not sufficiently high thermal expansion coefficient. The aim of the invention is to reduce the firing temperature and increase the thermal expansion coefficient. This goal is achieved by the fact that the glaze, including SiO, AlgO, ZrO,, Na2O, CaO, contains these components in the following amounts, wt.%: SiO2.33.0-40.0, 5-11.5 ZrOa13.2- 18.0 V Oz18.5-22.5, 0-6.0 CaO11.0-15.0 Glaze is prepared in the usual way of techno-geology. Frit is boiled at 13001350s for 3-4 hours. Frit is granulated in water and a slurry is made in wet mills in a ball mill, which is applied to the surface of articles. The firing temperature of the glaze is 920-80 ° C. The table shows the composition of the glaze of its properties. The composition of the glaze, wt.% SiOjL A12.
