Abstract
Metal carbide-containing refractory materials are prepared by pyrolysing blanks comprising reactive metal sources and carbon-containing precursors under fluid pressure, e.g., using hot isostatic pressing techniques. Refractory composites containing ceramic fillers, reinforcing materials such as carbon fillers, excess carbon or excess metal are readily prepared thereby.
Claims11
A process for producing a metal carbide-containing refractory material which comprises pyrolising under fluid pressure a blank comprising a reactive metal source and a thermoplastic carbon-containing precursor.
A process for the production of a metal carbide-containing refractory material which comprises:
- mixing a refractory metal or a derivative thereof with a thermoplastic carbon-containing precursor;
- compacting the resulting mixture into the form of a blank so as to remove any voids therefrom;
- and
- pyrolyzing said blank under conditions of fluid pressure, temperature and time such that said precursor is converted into carbon and undergoes reaction with said metal to form said refractory material.
