text: A common intermediate, which approximates a commonly found ratio of elements, is B 12 (CBC) = B 6.5 C. Quantum mechanical calculations have demonstrated that configurational disorder between boron and carbon atoms on the different positions in the crystal determines several of the materials properties - in particular, the crystal symmetry of the B 4 C composition and the non-metallic electrical character of the B 13 C 2 composition.
