FUSED-SALT SCRUBBING OF ZIRCONIUM TETRACHLORIDE
In the preparation of zirconium and hafnium metals, there are many indications that impurity levels control the physical and chemical properties of the metal. Methods of producing pure raw materials that could be reduced to highly pure metals were developed. Early work indicated that certain fused salts were highly efficient in the removal of impurities from gaseous zirconium tetrachloride. Workable fused salts were developed along with a continuous and highly efficient scrubber design which can be used to produce very pure zirconium tetrachloride. Metal made from the purified tetrachloride is shown to approach crystal bar metal in purity. Scrubber designs are discussed with recommended materials of construction. (auth)
