RAW COMPACT FOR GIVING THE MATERIAL DIMENSIONALLY STABLE LONG-TERM PROPERTIES AND A METHOD OF PRODUCING A CERAMIC MATERIAL WITH THE SAME

摘要

Raw compact (3) comprising a binding phase of calcium aluminate cement and one or more expansion-compensating additives for giving the material dimensionally stable long-term properties which raw compact has the capacity following saturation with a liquid reacting with the binding agents to form a chemically bound ceramic material, characterized in that the raw compact has a degree of compactness of 55-67 percent by volume solid phase.
