The high adsorption and chemical activity of titanium alloy powders (TiMo > TiV) having specific size and chemical compositions, and the nature of the surface and its specific energy characteristics permit one to use them effectively for the purification of argon and other inert gases from impurities such as water vapor, carbon dioxide gas, oxygen, and nitrogen. In agreement with the developed activity series the irreversible adsorption of impurities (1 vol. %) by the indicated powders can be controlled using powders or filters pressed from these powders by heating to temperatures of 500-700/sup 0/. The thickness of the filters can be established on the basis of the rate constants of the chemical reactions of the impurities with the TiMo and TiV powders obtained in this study.
