Abstract

The elastic moduli and their variation with pressure have been determined for three glass compositions in the K2OSiO2 glass system. The results may be summarized: {A table is presented}. Additionally, the heat capacities of the three compositions were determined over the temperature range of 320 to 700 K, and were used together with the other data to evaluate the thermal Grüneisen ratios. This parameter was found to increase with increasing K2O concentration, with values of 0.48, 0.63 and 0.69 for the three compositions indicated above. For comparison, the acoustic Grüneisen ratios evaluated from the variation of the moduli with pressure were found to be negative and also to increase with increasing K2O concentration.
