What is Yttrium Oxide used for?
Yttrium Oxide is also used to make yttrium iron garnets, which are very effective microwave filters. It is also a prospective solid-state laser material. Yttrium Oxide is an important starting point for inorganic compounds. For organometallic chemistry it is converted to YCl3 in a reaction with concentrated hydrochloric acid and ammonium chloride. Yttrium oxide was used in the preparation of pervoskite type structure, YAlO3, containing chrome ions.
