Abstract

537,251. Coating with selenium. NURNBERGER SCHRAUBENFABRIK GES. June 29, 1939, No. 18949. Convention date, June 1. [Class 82 (ii)] [Also in Group XXXVI] A thin layer of selenium in a plastic amorphous state at 160‹-170‹C. is applied to a foil of aluminium, for example, cooled, and the selenium face applied to an electrode plate, such as of nickel-plated iron, rolled to level off the layer and remove air, heated preferably to about 170‹C. to effect the crystallization of the selenium and stripped of the aluminium foil; surface amorphous selenium is then removed by vaporising at 215-219‹C. and finally a counter-electrode sprayed on, for example, of an alloy of zinc and cadmium, at such a temperature that a granular layer is produced. Specification 522,755 is referred to.
