摘要

The isothermal section of the phase diagram of Sc-Cr-B system at 800degreesC is constructed using the data of X-ray analysis. CrB2 dissolves up to 5 mol% of ScB2, and ScB2 dissolves up to about 20 mol% of CrB2. A new boride Sc2CrB6 was found and its crystal structure was established by single-crystal X-ray diffraction: Y2ReB6 type, space group Pbam, Z = 4, a = 8.7909(4), b = 11.0541(6), c = 3.2996(1) Angstrom, diffractometer Kappa CCD-Nonius, MoKalpha, R-F = 0.047, R-w = 0.064.
