Abstract

Experimental data which characterizes the stepwise transformation of tungsten — copper pseudoally in an oxidizing environment have been studied. The influence of pseudoalloy constituent elements, a size factor as well as a development of the reaction surface of the tested materials on the kinetics for oxidation processes have been established. Dependence of specific surface area fron the degree of dispergation has been presented. Necessity for correlation of the technological parameters of oxidation process has been established. This information is useful for developing technology of regeneration of tungsten from tungsten-containing materials.
