Crystals of Sc 2 AlB 6 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. Sc 2 AlB 6 single crystals were obtained in the form of prisms extending in the b-axis direction. The largest Sc 2 AlB 6 crystals prepared had maximum dimensions of about 0.4x0.4x4.2mm 3 . The values of the Vickers microhardness and the electrical resistivity of Sc 2 AlB 6 crystals are 12.7+/-0.8GPa and 43+/-8μΩcm, respectively. The oxidation of Sc 2 AlB 6 crystals starts at about 773 o C, and the weight gain after TG determination is 12.9mass% at 1200 o C. The oxidation products of Sc 2 AlB 6 crystals could not determined.
