An in situ method of producing dense TiB2 based composites is introduced. The composite was synthesised by silicothermic reaction in a reducing N2-CO atmosphere. Thermodynamic calculations have allowed the mechanism of the silicothermic reduction reaction to be deduced. Phase analysis by X-ray diffraction and microstructural examinations by SEM and EPMA were conducted.
