Abstract

Phase Transition in β-Rhombohedral Boron Near 550 K. -Differential scanning calorimetry indicates a structural phase transition of high-purity single crystal β-rhombohedral boron close to 550 K. This transition is responsible for discontinuities of numerous physical properties in this temperature range, which are interpreted assuming site hopping of boron atoms between regular, partially occupied crystallographic sites. -(HOFFMANN, S.; WERHEIT*, H.; Solid State Sci. 14 (2012) 11-12, 1572-1577, http://dx.
