The determination of the viscosity of liquid gallium over an extended nrange of temperature

On theoretical grounds measurements of the viscosities of liquids over as wide a temperature-range as possible are desired. Gallium is particularly suited for this purpose, and the viscosity of theolten metal has been measured between its melting point (approximately 30°C.) and 1100°C. This is a much wider range of temperature than has hitherto been recorded in viscosity-measurements. It has been necessary to devise a special technique on account of practical difficulties connected with surface films. At 1100°C. the viscosity decreases by only 2 per cent per 100°.
