FIELD: chemistry. SUBSTANCE: ceramic mixture contains, wt %: clay 38.0-40.0; kaolin 22.0-24.0; quartz sand 16.0-18.0; potsherd 4.0-6.0; calcium phosphate 8.0-10.0; pre-dried expanded pearlite 6.0-8.0. Firing temperature is 1070-1100°C. Articles cast from the slurry are aired off in moulds to moisture content of 18-21% when the cast article freely separates from the walls of the mould. The articles are then dried to moisture content of 1-6% and taken for firing at temperature of 1070-1100°C. A layer of low-melting glaze suspension is deposited on the surface of the fired articles, dried and then fastened by fusing at temperature of 870-900°C. EFFECT: low firing temperature of articles made from the ceramic mixture. 1 tbl
The invention relates to compositions of ceramic masses, which can be used for the manufacture of sanitary wares. Known ceramic material containing, by weight. %: clay 29,0; kaolin 27,0; quartz sand 28,0; ceramic skull 16,0; electrolytes 0,15-0,2; cobalt sulfate 0,03 [1]. The objective of the invention is to reduce the firing temperature of the products obtained from the ceramic body. The technical result is achieved in that the ceramic material, including clay, kaolin, silica sand, ceramic skull, additionally contains calcium phosphate and pre-expanded perlite in the following ratio, wt. %: clay 38,0-40,0; kaolin 22,0-24,0; quartz sand 16.0-18,0; ceramic skull 4,0-6,0; calcium phosphate 8,0-10,0; pre-expanded perlite 6,0-8,0. In the composition of the ceramic material can be used high-quality white burning clay and kaolin any of the fields. The table below shows the composition of the ceramic material.
The components are metered in the desired quantities loaded into a ball mill, pour the water and spend grinding components within 6-8 hours before the rest of 3-4% on a sieve 0056. The humidity of the slip take 36-46%. Using the obtained slurry in a plaster form being cast articles of desired configuration. Cast products podvalivaet forms to a moisture content of 18-21%, at which casting freely separated the t wall forms. The products are dried to a moisture content of 1-6% and direct the firing is conducted at a temperature 1070-1100°C. On the surface of baked products put a layer of fusible glaze suspensions, dry it and fix melt at a temperature 870-900°C. The source of information 1. Poluboyarinov D.N., Balcewicz V.L.
