Abstract

The shear viscosity η was measured as a detailed function of composition for liquid Hg based alloys containing 0–16 at% In in the temperature range from 320 K. to 520 K. A capillary viscometer of the Ostwald type was used for measurements. — The η increases linearly with the addition of In. This concentration dependence could be well explained by a simple hard sphere theory for η of liquid mixtures, in which the correction of back scattering took an important role. — The isothermal curves of ∂η/∂T show a slight depression at a few at% In, particularly at lower temperatures. This phenomenon appears to be related to higher order correlation (HOC) effects, which have been proposed recently for some liquid Hg based alloys by the present authors.
