  • Metal carbide-containing refractory materials
    Patent number: 6013226
    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.
