## Abstract Apparatus is described for experimentally determining diffusion coefficients in denseβgas systems to pressures of 15,000 lb./sq. in. abs. Tests were made with the hydrogenβnitrogen and methaneβethane systems at 104Β°, 139Β°, and 171Β°F. to 10,000 lb./sq. in. abs. and with the nitrogenβmeth
of UC with oxygen gas. When the intricacies of these processes are unravelled, they may provide further insight into the strticture and some of the other properties of UC. The single crystals of uranium monocarbide were prepared by Mr. A. K. Smalley and Mr. T. B. Johnson. Their assistance is gratef
In this paper, a theory of multiphase diffusion in binary systems is developed. Molar volume and the pa~itioning of the diffusing species among the product phases are considered. The growth and consumption of various product phases as the diffusion reaction progresses are described in terms of expli
