First Uses of the Periodic Table Element - Yttrium.The Evolution of Yttrium: From Luminescence to Advanced Technologies.Yttrium, a silvery metallic element, was first discovered in 1794 by the Finnish chemist Johan Gadolin. Since its initial identification, yttrium has found diverse applications in various fields, ranging from luminescence in television screens to catalysts in chemical reactions. Nevertheless, as technology advanced and new materials were discovered, yttrium gradually lost its prominence in some of its traditional applications. This article explores the first uses of yttrium and delves into the reasons behind its declining usage.
