Determination of Diffusivities in Liquid Metals by Means of Temperature-Gradient Zone Melting

J. H. Wernick

Open publisher page 46 citations

Abstract

Diffusivities of liquid alloys of Ge–Al, Ge–Au, and Si–Al have been measured by a new technique. Called temperature-gradient zone melting, the technique involves passing extremely thin molten zones through a solid crystal by means of a temperature gradient. Preliminary values of the diffusivities fall in the 10—5 cm2/sec range at temperatures of 530°C to 700°C.
