The Production of the Light Rare Earths in the Massive Metallic State
Description:
Abstract: "Cerium, lanthanum, praseodymium and neodymium metals have been prepared in high purity in the massive state by reducing the appropriate rare earth chloride with calcium metal, using iodine as an auxiliary oxidant. Vacuum remelting of the product metal is employed to eliminate small amounts of calcium and magnesium. Attempted reductions of samarium and yttrium halides have not been successful."
