METHOD FOR THE MANUFACTURING OF A POWDERED MATERIAL, THE POWDERED MATERIAL AND A CERAMIC MATERIAL MANUFACTURED THEREFROM

摘要

Powdered material, the binder phase of which mainly consists of a cement-bas ed system, which powdered material has the capacity following saturation with a liquid reacting with the binder phase to hydrate to radiopaque and chemicall y bonded ceramic material. According to the invention, said binder phase mainl y consists of CaO~Al2O3 (ss) and/or 3CaO~Al2O3 (ss). The material also contain s one or more heavy atom types with a density over 5g/cm3. The invention also relates to a method for manufacturing the powdered material and the chemical ly bonded ceramic material formed from the powdered material, in which said binder phase has a mol ratio Al2O3~3H2O (ss) to 3CaO~Al2O3~6H2O (ss) of a maximum of 2:1.
