Abstract

The viscosity of liquid sulfur up to 9.7 GPa and 1067 K was measured using the in situ x-ray radiography falling sphere method. The viscosity coefficients were found to range from 0.11 to 0.69 Pa s, and decreased continuously with increasing pressure under approximately constant homologous temperature conditions. The observed viscosity variation suggests that a gradual structural change occurs in liquid sulfur with pressure up to 10 GPa. The L-L′ transition in liquid sulfur proposed by Brazhkin ei al (1991 Phys. Lett. A 154413) from thermobaric measurements has not been confirmed by the present viscometry.
