Electrophysical Properties of Composites Based on Hydrogenated Titanium with Different Contents of Thermally Expanded Graphite

Abstract

The formation of carbon-containing composites based on metals opens the prospect of combining the advantages of their components and manifesting new electrophysical properties, which are not characteristic of the original materials. Mechanical synthesis of hydrogenated titanium (TiH) and thermally expanded graphite (TEG) powders leads to such composites formation. As shown, the increase by 1.65 and 6.3 times in their electrical conductivity is observed in comparison with original TiH and TEG components, respectively. It is due to an increase of free electrons in the TEG because of their transport from the metal component.
