SiO2–Na2O–B2O3 density: A comparison of experiments, simulations, and theory

Abstract : This paper is devoted to a comparison of experimental, simulation, and theoretical results on the density of SiO 2 – B 2 O 3 –Na 2 O glasses. It is found that theoretical and simulation densities do compare favorably with experimental values yet simulations give a better estimate of the density of the samples. Furthermore, the structural make-up (i.e. types of borate and silicate units) of the ternary glasses and the volume of the elementary units have also been investigated with simulations and compared to theory.
