Abstract
Traces of oxygen-containing compounds are removed from technically pure zinc by intimately mixing the zinc at a temperature lying within the congealing range with a material having a higher fusing point than the zinc and a considerable affinity for oxygen. The material may be a metal, e.g. copper, magnesium, or aluminium, a mixture of a metal and a metal oxide, e.g. copper and cuprous oxide, a metal compound such as a chloride or sulphide, or an ammonium compound, e.g. ammonium chloride. To ensure intimate contact relative motion may be produced between the zinc and gratings, grilles, plates, &c. of the de-oxidizing material. The congealing range for technically pure zinc lies between 419 DEG C. and an upper temperature which may vary between 428 DEG C. and 441 DEG C. If the metal used for deoxidizing alloys with the zinc it may be subsequently removed, e.g. by liquation. The treatment is stated to reduce considerably the tendency of the zinc to oxidize and to alloy with other metals or metalloids. The fluidity is also increased.
