A process for the production of dense silicon nitride materials by the nitriding of moulded bodies of silicon powder, silicon nitride powder and sintering additives under normal pressure and sintering of the moulded bodies at normal nitrogen pressure as well as silicon nitride materials produced correspondingly.

Process for the production of dense silicon nitride materials

A molding compound is disclosed which is useful in producing inorganic sintered moldings, which contains, in addition to an inorganic powder, a binder system containing a thermoplastically processable, partially crystalline polyester and an additional low molecular weight compound which may react with the polyester. A process is disclosed for preparing a sintered molding by injection molding of the molding compound, removal of the binder system, and sintering.
