Abstract

Pieces of compact cuprous oxide are heated at 400-650 DEG C. and then quenched, whereby their electrical resistance is lowered. When the bodies are produced by heating shaped pieces of copper to 1000 DEG C. or above in an oxidizing atmosphere they may be cooled to and retained at the required temperature and then be quenched. The product may be used in the construction of light-sensitive cells, thermopiles, or rectifiers.
