Nutpool Materials

The specimens examined were completely characterized within the homogeneity range of the carbide phase (8.8–20.0 at.% C, i.e. B_10.4CB₄C). An X-ray study of the lattice dimensions together with accurate measurements of the density of the compounds examined allowed us to determine the number n of atoms contained in the unit cell. The value of n varies linearly with the carbon content between B₁₂(CBC)_0.666B_1.333 (“B_10.4C”; n = 15.33 atoms per unit cell) and B_12−xC_xC¦B_xC_1−xC) (“B_10.4C”; 0 < x < 1; n = 15.0 atoms per unit cell).
