Summary

Titanium diboride (TiB2) was synthesized by the self-propagating fast reaction of the basic elements Ti and B as well as from the slower reaction of Ti with B4C. The heat released from these highly exothermic reactions is sufficient to heat the product TiB2 above its melting point without other external heating; the synthesized TiB2 specimens had densities 96.6% of theoretical, Vickers hardness of 2520±130 kg/mm2 for a 0.2-kg load, and three-point-flexure strength of 568 735 ±38 087 kPa (82 488±5524 psi).
