MIXTURE FOR PREPARING CERAMIC MATERIAL FOR THERMALLY, MECHANICALLY AND ELECTRICALLY DEMANDING APPLICATIONS

摘要

The working mixture consists of 36 to 48 mass parts non-calcinated talc, 38 to 52 mass parts of a clay constituent and 12 to 21 mass parts of aluminium oxide with possible admixtures of catalytically active metals or their compounds if the material is to be applied as a catalyst. The working mixture is modified by dry or wet milling or is granulated and moulded by common ceramic technologies, preferably by pressing and extruding. The material is burned to temperatures of 1,200 to 1,500 degrees C.
