Benefits of technology

[0033]The literature regarding the explosive behaviour of wires treated with electrical current is very extensive. The phenomenon of the explosive degradation of wire has been known since Faraday's time. As early as in the XIX century, it was noted that a high-density current causes the violent disintegration of a conductor. Thus, at a comparatively early stage of electrical and material studies during the XIX century, the melting (softening) currents of metals were determined. It turned out that under the influence of high-amperage direct currents, most metals undergo rapid softening. This occurs when the internal, electrical charge potential measured per centimeter of length of

Problems solved by technology

However, intensive external cooling of the metal results in an increase of the critical currents mentioned herein.
The authors' experiments showed that even with the most efficient me

Embodiment Construction

[0039]Longitudinal forces and the explosive degradation of wires: In the literature cited, published in Poland in 2001, it is shown that longitudinal forces occur in every conductor under the electrical current flow. Such forces are strictly quantum mechanical in character. The source of the longitudinal forces in metallic conductors is explained therefore in transfer of electrons which are colliding with the crystalline lattice of the conductor (phonons) as well as with impurities and structural metal crystal defects.

[0040]Conductor explosions as a source of nano-particles: Metallic conductors subjected to the high-density currents “break up into fragments”. This occurs when forces resulting from the collisions with metal ions exceed metal cohesive forces. The degrading metal forms an immense number of microscopic metallic fragments. The technique in which such a degradation takes place in a liquid medium is of particular practical importance. Metallic fragments formed as a result ...
