Metod att framställa ett pulvermaterial, pulvermaterialet samt ett keramiskt material framställt därav

摘要

Powdered material, the binder phase of which mainly consists of a cement-based system, which powdered material has the capacity following saturation with a liquid reacting with the binder phase to hydrate to a radiopaque and chemically bonded ceramic material. According to the invention, said binder phase mainly consists of CaO.Al₂O₃ (ss) and/or 3CaO.Al₂O₃ (ss). The material also contains one or more heavy atom types with a density over 5 g/cm³. The invention also relates to a method for manufacturing the powdered material and the chemically 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.
