Abstract [en]

Crystals of Sc2AlB6 were grown using scandium oxide and elemental boron as starting materials in a self-component aluminum solution under an argon atmosphere. The growth conditions for obtaining single crystals of relatively large size were investigated. Sc2AlB6 single crystals were obtained in the form of prisms extending in the b-axis direction. The largest Sc2AlB6 crystals prepared had maximum dimensions of about 0.4×0.4×4.2 mm3. The values of the Vickers microhardness and the electrical resistivity of Sc2AlB6 crystals are 12.7±0.8 GPa and 43±8 cm, respectively. The oxidation of Sc2AlB6 crystals starts at about 773°C, and the weight gain after TG determination is 12.9 mass% at 1200°C. The oxidation products of Sc2AlB6 crystals could not determined.
