RI 5588 Preparation Of High-Purity Yttrium By Metallic Reduction Of Yttrium Trichloride ? Summary

This investigation was made as part of a larger program to develop basically new methods for preparing yttrium metal in high-purity form. It was performed under a cooperative agreement between the U.S. Atomic Energy Commission (AEC) and the Federal Bureau of Mines. Laboratory-scale tests were made to devise methods for preparing high-purity, anhydrous yttrium trichloride, for reducing the yttrium trichloride with sodium or lithium, and for consolidating the resulting yttrium sponge into ingots.
