Abstract

The reduction of the behaviour of melt properties in the glass transition region to a universal set of parameters that describe the evolution of fictive T during reheating allows the extension of dilatometric molar expansivity data into the liquid state using corresponding scanning calorimetric heat capacity data. This method yields excellent agreement with molar expansivity obtained by high-T densitometry. The combination of the methods allows the error associated with molar expansivity to be reduced to +- 1%. The behaviour of Na (sub 2) Si (sub 3) O (sub 7) is discussed in detail.
