QSPR Models for Density

Density, one of the most important properties in industrial glass production, is perhaps the simplest physical property that can be measured nevertheless its dependence upon composition is not straightforward. A number of linear expressions, empirically 

In this context, the successful example of the QSPR approach for the prediction and interpretation of density of multicomponent silica-based bioglasses offered by the studies of Linati et al. [33] and Lusvardi et al. [34] is of great significance. In fact, a unique QSPR model derived is able to rationalize the variation of density in four series of glasses made up of three to five different components. 

The four series of glasses studied have the following general formula
