Abstract
1330252 Copper sulphide body E I DU PONT DE NEMOURS & CO 19 April 1971 [8 April 1970] 25999/71 Heading C1A [Also in Division H1] A copper sulphide body for use as a voltaic cell cathode has a porosity of at least 50% and a resistivity of less than 0À5 ohm cm. Such a body is formed by pressing a mixture of finely divided sulphur and copper into the form of the cathode body at below the melting point of sulphur and heating the body at atmospheric pressure to effect reaction. Preferably the sulphur to copper atom ratio is between 1À1 : 1 and 1 : 1, and the mixture may be aged at below the melting point of sulphur before being pressed.
