Chromium boride crystals were obtained by the high temperature metal (copper, lead or tin) solutions using chromium metal and boron powders as starting materials in an argon atmosphere. CrB and CrB_2 crystals were obtained as a single phase, however, Cr_3B_4 and Cr_2B_3 were obtained invariably as a phase mixture for various atomic ratios of the starting material in molten metal solutions. The largest CrB and CrB_2 crys tals were obtained froun Cu solution. CrB crystals were obtained in the form of pillar shape extending to a axis or c axis and thin plates with well developed {010} faces, and CrB_2 crystals were obtained in the form of nearly spherical polyhedron. The largest crystals pre pared had the maximum dimensions of about 0.12 mm×0.13 mm×3.30 mm for CrB and 30μm for CrB_2. The results of unit cell dimension and chemical analy sis of CrB and CrB_2 crystals are also present.
