Abstract (en)
[origin: WO8300325A1] TiB2-carbon composites are produced by mixing the raw materials comprised of carbon, TiB2, pitch, and other reactants, forming a shaped article, processing in a nitrogen atmosphere up to 2100<o>C, and in a noble gas above 2100<o>C, by pressureless sintering of TiB2 or other refractory hard metal powder, or by molding or extrusion of plastic mixes of binder and particulate carbon and refractory hard metal.
