Abstract

FIELD: ceramic industry.
SUBSTANCE: invention relates to production of articles of fine ceramics. Mixture for making fine ceramics contains, wt.%: low-melting clay 30.0-32.0; refractory clay 25.0-27.0; boron glass 19.0-20.0; expanded pearlite 18.0-19.0; pyrite cinders 1.2-1.7; talc 2.6-3.85; copper sawdust 0.1-0.2. Components are dosed in required amounts, then ground until passage through sieve no. 008, and mixed. From obtained mixture with humidity 9-13 % required configuration items are moulded, which are fired at temperature 1,080 to 1,120 °C. Subsequent decoration of fired articles with colored fusible glazes and enamel is possible.
EFFECT: technical result of invention is higher heat resistance of articles.

Description

Изобретение относится к производству изделий тонкой керамики.The invention relates to the production of fine ceramics.

Известна шихта для изготовления тонкой керамики следующего состава, мас. %: глина легкоплавкая 30,0-32,0; глина огнеупорная 21,0-23,0; стекло борное 14,0-17,0; перлит 26,0-28,0; пиритные огарки 1,9-7,0 [1].Known mixture for the manufacture of fine ceramics of the following composition, wt. %: low-melting clay 30.0-32.0; refractory clay 21.0-23.0; boron glass 14.0-17.0; perlite 26.0-28.0; pyrite cinders 1.9-7.0 [1].

Задачей изобретения является повышение термостойкости изделий из шихты.The objective of the invention is to increase the heat resistance of products from a mixture.

Технический результат достигается тем, что шихта для изготовления тонкой керамики, содержащая глину легкоплавкую, глину огнеупорную, стекло борное, вспученный перлит, пиритные огарки, дополнительно содержит тальк и медные опилки при следующем соотношении компонентов, мас. %: глина легкоплавкая 30,0-32,0; глина огнеупорная 25,0-27,0; стекло борное 19,0-20,0; вспученный перлит 18,0-19,0; пиритные огарки 1,2-1,7; тальк 2,6-3,85; медные опилки 0,1-0,2.The technical result is achieved in that the mixture for the manufacture of fine ceramics, containing low-melting clay, refractory clay, boron glass, expanded perlite, pyrite cinders, additionally contains talc and copper filings in the following ratio of components, wt. %: low-melting clay 30.0-32.0; refractory clay 25.0-27.0; boron glass 19.0-20.0; expanded perlite 18.0-19.0; pyrite cinders 1.2-1.7; talc 2.6-3.85; copper filings 0.1-0.2.

В табл. 1 приведены составы шихты.In the table. 1 shows the composition of the charge.

Стекло варят при температуре 1000°С, расплав гранулируют в воду. Компоненты дозируют в требуемых количествах, размалывают до прохождения через сетку №008 и смешивают. Glass is boiled at a temperature of 1000 ° C, the melt is granulated in water. The components are dosed in the required quantities, ground until passing through mesh No. 008 and mixed.

Из полученной шихты с влажностью 9-13% формуют изделия требуемой конфигурации, которые обжигают при температуре 1080-1120°С. Возможно последующее декорирование обожженных изделий цветными легкоплавкими глазурями и эмалями. Термостойкость изделий из шихты (нагрев до 100°С - охлаждение до 20°С) составит не менее 200 циклов.From the resulting mixture with a moisture content of 9-13%, articles of the required configuration are molded, which are fired at a temperature of 1080-1120 ° C. Subsequent decoration of burnt products with colored fusible glazes and enamels is possible. Heat resistance of products from the charge (heating to 100 ° C - cooling to 20 ° C) will be at least 200 cycles.
