APPARATUS FOR THE PURIFICATION OF CALCIUM
Abstract
The present patent claims and describes an apparatus adapted to carry out a new process for the purification of calcium containing an alkali metal as impurity. The process consists of distilling the impure caldium in the presence of an inert gas and at a reduced pressure, condensing substantially pure calcium on a condensing surface of iron or a ferrous alloy and condensing the alkali metal on a separate surface, the two condensing surfaces being maintained at suitable temperatures by separate cooling means.
