Study of the Interaction of Lanthanum, Neodymium and Gadolinium Oxides with Ammonium Fluoride

摘要

Rare earth elements (REEs) play the important role in our everyday lives, as crucial components in a range of products. In this work, the interaction between lanthanum, neodymium, gadolinium oxides and ammonium fluoride was investigated. The transformation proceeds through the formation of rare earth elements intermediate fluoride complexes with different composition formation, which is confirmed by TGA and DSC analyzes.
