Book Description
The transport property which is most fundamentally related to forces between unlike molecules is the ordinary diffusion due to concentration gradients. Unfortunately, this property and its dependence upon temperature have not been systematically studied experimentally, with the result that the literature does not contain the data necessary to obtain good force constants for the introduction of unlike molecuels. The present work describes an experimental method for determining diffusion coefficients, based on the variation of thermal conductivity with composition in binary mixtures which is capable of being used over a wide range of temperature. Experimental results for the systems n-butane-hydrogen, sulfur hexafluoride-hydrogen, argon-hydrogen, and argon-helium are given for a temperature range from 10°C. to 140°C.

Book Description
This monograph describes mathematical models that enable prediction of phase compositions for various technological processes, as developed on the base of a complex physico-chemical analysis of reaction. It studies thermodynamics and kinetics of specific stages of complex pyrometallurgical processes involving boron, carbon, sulfur, tungsten, phosphorus, and many more, as well as their exposure to all sorts of factors. First and foremost, this enables to optimize processes and technologies at the stage of design, while traditional empirical means of development of new technologies are basically incapable of providing an optimal solution. Simulation results of metals and alloys production, welding and coating technologies allow obtaining materials with pre-given composition, structure and properties in a cost-saving and conscious manner. Moreover, a so-called "inverse problem", i.e., selecting source materials which would ensure the required results, cannot be solved by any other means.
