The Process of Hydrostatic Compaction of B2O3 Glass

Part of the Materials Science Research book series (MSR, volume 5)


Upon application of high pressure, glass exhibits both elastic and anelastic behavior even at room temperatures. The consequence of anelastic behavior has been recognized as an “irreversible” densification. The technique developed permitted measurement of the instantaneous volume of B2O3 glass under hydrostatic pressure up to 22 kbar. It was observed that (1) anelastic volume strain is highly nonlinear in pressure, (2) apparent bulk viscosity may be lower than 1015poise at onset of pressure application and tends to approach infinitely large value as time advances, and (3) more than one ordering parameter is necessary to be consistent with observed compaction under pressure.
