According to the invention, said binder phase mainly consists of CaO.AlO(ss) and/or 3CaO.AlO(ss). The material also contains one or more heavy atom types with a density over 5 g/cm. 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 AlO.3HO (ss) to 3CaO.AlO.6HO (ss) of a maximum of 2:1.
