Abstract

Barium is produced in a closed receptacle such as an electric discharge tube, electric incandescent lamp, &c., by the reduction of barium oxide by means of sodium vapour. The sodium may be introduced electrolytically through a glass wall of the receptacle or of a vessel connected therewith.
