Abstract Scope |
The largest outputs of rare earth mines are byproducts cerium and lanthanum. The need to separate them from more valuable elements burdens supply chains. Promoting cerium and lanthanum demand can diversify the economics of rare earth mining improving rare earth supply chain stability. One avenue for increasing byproduct rare earth element demand is use in aluminum alloys, an application for cerium and lanthanum offering benefits to manufacturing such as energy reduction and improved throughput. Experimental materials science and economic implications of Al-rare earth element alloys will be discussed. We show that Al-La/Ce alloys have good mechanical strength, in some formulations can be used without heat treatment, and are castable. This report presents the use of cerium and lanthanum in aluminum alloys as an example of supply chain focused approaches to technological development benefiting stakeholders at all production steps.
