Abstract
In the present study particle powders of copper coated with thin films of organometallic complexes were pressed and then heat treated. The complex compounds were thermally decomposed to carbide particles of uniform dimension or to fine oxide particles; these particles were homogeneously dispersed in the alloys, thus permitting the production of the conductive materials having fairly low or negative temperature gradient of resistance to keep high conductivity at higher temperature. It may be said that this type of new conductive materials overthrows the Matthissen's rule. Thus deviation from the Matthissen's rule is particularly re-markable in the samples added with Ni(AA)2, Ti(AA)3, 1Mn4Ni(AA)2 and SmCo5(AA)2. This deviation may be attributed to s-d interaction of the dispersed amorphous transition metal compounds and matrix copper atoms.
