| Abstract Scope |
Scandium has emerged as an important niche industrial material over the last 15-20 years, supported by growth in demand for the oxide in solid oxide fuel cells. Scandium as a metal is remarkable alloying agent for aluminum at levels below 1 weight %. It imparts strength, fatigue resistance and stiffness by spontaneously forming Al3Sc nanoparticles. The current decade has also seen the deployment of high scandium / aluminum alloys containing 20-40 weight % scandium, mainly in radio frequency signaling in 5G antennas. In this paper, we review technologies used to produce scandium-aluminum alloys (including electrolytic and metallothermic approaches) and present data on work carried out by a consortium of the authors' companies to manufacture both scandium-aluminum alloys, and scandium metal. |
