Abstract (en)
[origin: EP1236808A2] Metal powder composite material contains at least two oxides enclosing metal powder particles. The oxides form a common phase. An Independent claim is also included for a process for the production of a composite material comprising pressing a starting material into molded bodies, pyrolyzing the separating agent by heating in a non-reducing atmosphere to oxides, and reacting the oxides with each other forming a common phase. Preferred Features: The metal powder is made from iron. The common phase is a silicate- or boron-containing glass or a defined compound selected from mixed oxides with a spinal structure, metal phosphates and metal silicates. The mixed oxides are selected from Al2MgO4, Al2ZnO4, Al2MnO4, Al2FeO4, Fe2MgO4, Fe3O4, Fe2ZnO4, Fe2MnO4, Fe2NiO4, Cr2FeO4 and Cr2MgO4.
