Abstract
The effect of pressure on the viscosity of B2O3 glass has been determined by a high pressure capillary flow method up to about 2000 kg/cm2, at two temperatures, 516° and 359°C. The results are satisfactorily represented by the expression η = η0eαp, with α = 4.6·10−4 cm2/kg at 516°, α = 15·10−4 cm2/kg at 359°. The ratio of the viscosity at 1000 kg/cm2 to the viscosity at 1 atmosphere is therefore 1.58 at 516°, 4.48 at 359°. The results are briefly compared with those for organic liquids.This publication has 11 references indexed in Scilit:
