Abstract

PURPOSE: To enhance the quality of metallic Ca by passing Ca vapor through a CaO packed bed to capture impurity Al when CaO is thermally reduced with Al or the llke in a vacuum and distilled.
CONSTITUTION: Briquettes 2 obtd. by molding CaO and powder of Al or the like are packed in a vacuum retort 1 in a heating furnace 3, and after evacuating the retort 1, the briquettes 2 are heated. Metallic Ca reduced by the vacuum heating is evaporated, and Ca vapor passes through a layer 11a of CaO granules in a heat insulated container 11 and condenses on a face of condenser 4. At this time, Al having a lower vapor pressure than metallic Ca is captured by the CaO layer 11b, and the purity of metallic Ca 5 condensed on the condenser 4 is enhanced.
