Structure and Properties of Alloys Obtained by Aluminothermic Reduction of Deep-Sea Nodules

“…Aluminothermic processes [ 28 ] are based on the reaction of metal oxide with aluminum, which acts as a reducing agent. The reaction is driven by the high affinity of aluminum to oxygen.…”

Aluminothermic reduction of CeO2: mechanism of an economical route to aluminum–cerium alloys

“…2 Metallothermic reactions remain a crucial technology applied in the iron thermite reaction for welding of train tracks and the industrial production of metals such as Be, Ti, Ta and the rare earth elements through the reduction of their halides by Mg, Na or Ca. 3,4 Rare earth elements tend to be co-located in ore deposits and are treated together in extraction. Cerium is the majority element in most deposits, and the growing need for Nd, Pr and the heavy lanthanides in permanent magnets and other energy transition technologies results in costly stockpiling of cerium oxide that has low demand.…”
