Comparison of methods used for the calculation of density, refractive index and thermal expansion of oxide glasses


Glass Technology, vol. 44, no. 4, August, 2003, p 156-166


Abstract: A generalized criterion "epsilon" for evaluating the quality of glass property calculations is proposed. This criterion permits the comparison of the quality of existing methods of calculation of a given property in a given composition area. Values of "epsilon" for ten of the most well known calculation methods and a new method by Priven are compared. The SciGlass Information System containing experimental property data for more than 130'000 glasses* was used. Recommendations concerning the selection of the best methods of glass property calculations in various composition areas are made.
