Anelasticity Of A Mixed Alakali Silicate Glass At High Pressures

The effect of hydrostatic pressure on the stress relaxation of 0.05 Na2o, o.95 K2O, 3.00 SiO2 mixed alkali silicate glass was studied at 75 C between ambient pressure and 6 kbar. The activation volume of diffusion was found to be -4.2cm3/mole. It is proposed that a re-equilibration of the defect population at pressure gives rise to the negative activation volume of diffusion.
