Bismuth Trioxide

Bismuth Trioxide (Bi2O3) is the prevalent commercial oxide of bismuth. As a precursor to the preparation of other compounds of bismuth, bismuth trioxide has specialized uses in optical glass, flame-retardant paper, and, increasingly, in glaze formulations where it substitutes for lead oxides.

Europium(III) Oxide
Europium(III) Oxide (Eu2O3) is a chemical compound of europium and oxygen. Europium oxide has also other names as Europia, Europium trioxide. Europium oxide has a pinkish white color. Europium oxide has two different structures: cubic and monoclinic. The cubic structured europium oxide is almost same as magnesium oxide structure. Europium oxide has negligible solubility in water, but readily dissolves in mineral acids. Europium oxide is thermally stable material that has melting point at 2350 oC. Europium oxide’s multi-efficient properties like magnetic, optical and luminescence properties make this material very important. Europium oxide has an ability to absorb moisture and carbon dioxide in atmosphere.
