Abstract

A simple experimental method is proposed for determining diffusion coefficients from amounts of gas absorbed by metal powders. An analysis is made of errors in the measurement of D by the new method, and optimum experimental conditions are indicated. Data yielded by a study of the diffusion of hydrogen in LaCo5 show that DH293 → LaCo5 can be calculated by this method with satisfactory accuracy.
