Erbium Oxide Properties                                                    Erbium Oxide which has a pink color with a cubic crystal structure, is synthesized from the metal  erbium . Erbium metal tarnishes slowly in air.  Erbium burns readily to form Erbium Oxide. Erbium oxide is insoluble in water and soluble in mineral acids. Er2O3 readily absorb moisture and carbon dioxide from the atmosphere. It can react with acids to form the corresponding Erbium (III) salts. For example, with hydrochloric acid, the oxide follows the reaction Er 2 O 3  + 6 HCl → 2 ErCl 3  + 3 H2O to form erbium chloride. One interesting property of erbium oxides is their ability to up convert energy. Energy up conversion takes place when infrared or visible radiation, low energy light, is converted to ultraviolet or violet radiation higher energy light via m...
