The Relation between the Physical Properties and the Structure of Glass. Part I. Variations of the Physical Properties with Time
JSGT 1947 V31 T050-T073
The X-ray diffraction patterns of liquids and glasses are compared; it is shown that the similarities between them enable a qualitative application to be made to glasses of some theoretical work on the liquid state by J. D. Bernal. In this way a satisfactory account may be given of the time-variation of the physical properties of glasses in the temperature range in which their viscosity increases above about 1013 poises. This account is given in terms of a random network structure and involves no considerations of aggregation or association.
