How Cerium and Lanthanum as Coproducts Promote Stable Rare Earth Production and New Alloys

The largest outputs of rare earth mining are the low-value byproducts cerium and lanthanum, which burden supply chains because they must be separated from more desirable earths used in magnet production. Promoting demand for lanthanum can potentially diversify economics improve chain stability all elements. A promising avenue increasing byproduct element is their use aluminum alloys; an application offering multiple benefits to manufacturing such as energy reduction improved throughput. Experimental materials science economic implications Al-rare alloys will discussed. We show that Al–La/Ce have elevated mechanical strength compared traditional alloys, some formulations without heat treatment, possess a highly castable eutectic microstructure. This report presents example how focused approaches technological development benefit stakeholders at every step
