CERAMIC BODY FOR MANUFACTURING INSULATORS Russian patent published in 1999 - IPC

FIELD: manufacture of electroceramic materials intended for making low-voltage insulators, suspended linear high- voltage insulators or other electroceramic products. SUBSTANCE: ceramic body comprises refractory clay, alumina, quartz sand, kaolin, and alkali-containing alum. Alkali-containing alum is alkali flow of caprolactam production, ratios of components being as follows, wt %: refractory clay, 30-40; alumina, 20-30; quartz sand, 8- 10; kaolin 20-30; alkali flow of caprolactam production, 0.5-1.0. The resulting products have high tensile strength, bending strength and electrical strength. Method makes it possible to reduce firing temperature of ceramic body and to retain electrochemical strength. EFFECT: improved properties of the ceramic body. 3 cl, 3 tbl
