CHEMICALLY BOUND CERAMIC PRODUCT, METHOD FOR ITS PRODUCTION,TOOL TO BE USED IN EXECUTION OF THE METHOD AND INTERCHANGEABLE PART ON THE TOOL

摘要

Raw compact (3) comprising a binding phase of one or more powdered binding agents, which raw compact has the capacity, following saturation with a liqu id reacting with binding agents, to form a chemically bound ceramic material, a nd which raw compact preferably has a degree of compactness of 55-67 percent by volume solid phase. According to the invention, the raw compact (3) also comprises one or more expansion-compensating additives adapted to give the material dimensionally stable long-term properties. The invention also relat es to a method of manufacture of the ceramic material, and a compaction device and a compaction body for compacting the saturated raw compacts.
