Based on a liquid–glass transition model a phonon‐assisted structural transition between atomic configurations developed recently, the temperature dependence of the specific volume, the high frequency longitudinal and shear moduli, the hypersonic longitudinal and transverse sound velocities of vitreous and molten B 2 O 3 are expressed directly or indirectly in terms of n R , which is a concentration of structural component of B 2 O 3 obtained by our phonon‐assisted structural transition model to B 2 O 3 . All these theoretical results are in good quantitative agreement with the experimental data.
