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.Al<SUB>2</SUB>O<SUB>3 </SUB>(ss) and/or 3CaO.Al<SUB>2</SUB>O<SUB>3 </SUB>(ss). The material also contains one or more heavy atom types with a density over 5 g/cm<SUP>3</SUP>. 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 Al<SUB>2</SUB>O<SUB>3</SUB>.3H<SUB>2</SUB>O (ss) to 3CaO.Al<SUB>2</SUB>O<SUB>3</SUB>.6H<SUB>2</SUB>O (ss) of a maximum of 2:1. |
