WebIn the chromium-boron phase diagram there is evidence of the presence of six chromium borides, which include Cr 2 B, Cr 5 B 3, CrB, Cr 3 B 4, CrB 2 and CrB 4 . Among these borides, chromium diboride (CrB 2) is of particular interest, showing the higher melting temperature, a good electrical conductivity and a hardness of the order of 20 GPa [3 ...
