The study presents a possible mechanism to produce carbides and diborides of transition metals, such as titanium, vanadium, chromium zirconium. carbothermal synthesis metal has defined the direct dependence between thermodynamic stability oxides temperature range reduction onset (the stronger oxide, higher value is). It reaches 2000-2100, 1500-1600, 1300-1400 2100-2200°C for TiC, VC 0,88 , Cr 3...
