To estimate the physical characteristics of cubic boron arsenide, Keating’s model of force constants and Harrison’s method of bonding orbitals are used. The harmonic and anharmonic characteristics are considered. Comparison of the results with experimental data and other calculations shows the adequate applicability of the approach.
