摘要
The discrepancy between the surface compression measured and that calculated using molar volume data was discussed. Investigation about the physical properties responsible for the generation of stress in ion-exchanged glasses was presented. A progressive stress measurement technique was used to show that the surface layers had higher thermal expansion coefficient relative to that of parent. A unified model was developed to account for the low magnitudes of observed compression.
