The preparation of a crystalline form of boron, later referred to as α-rhombohedral1 was reported first in 1958 by McCARTY et al. (1958), who had found red boron crystals in the deposit formed under the pyrolysis of boron triiodide. However, as DECKER and KASPER (1959) stated, α-boron had earlier been prepared by the decomposition of boron hydride and had also been found in some commercially prepared boron samples.
