(Discontinued) Ultrafine Yttrium Oxide (Y2O3)

Yttrium Oxide is Y2O3. It is an air-stable, white solid substance. Yttrium oxide is used as a common starting material for both materials science and inorganic compounds. It is the most important yttrium compound in materials science and is widely used to make YVO4 europium and Y2O3 europium phosphors that give the red color in color TV picture tubes. Yttrium oxide is also used to make yttrium iron garnets, which are very effective microwave filters. In inorganic synthesis, 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.
