  • Process for the continuous production of solid alkali metal strands
    Patent number: 4536938
    Abstract: A process is described for the production of solid alkali metal strands, whereby molten alkali metal is introduced to an extrusion apparatus and is continuously cooled down as the metal travels along a section of the extrusion apparatus by means of a worm. There is a temperature gradient between the point at which the molten alkali metal enters the extruder down to a temperature below its solidification point near the nozzle, at which the metal is still sufficiently ductile for extrusion, and is then fed to a nozzle for shaping into the stands.
