Description
Europium(III) oxide is a rare-earth oxide supplied in ROTI®METIC quality at 99,995 % (4N₅). It is characterised by CAS number 1308-96-9, empirical formula Eu₂O₃, molar mass 351,92 g/mol and density 7,42 g/cm³. The boiling point is given as 4118 °C, and the EG number is 215-165-6. This 5 g plastic pack provides a convenient quantity for solid-state chemistry, phosphor-related studies and other laboratory work that relies on a high-purity europium source. The material comes from manufacturer Carl ROTH and is suited to research environments where controlled rare-earth purity is essential for reproducible results. Documented molar mass and density values assist with batch calculations and material balances, while the ROTI®METIC purity class addresses demands for minimal impurity contribution. The plastic packaging supports orderly storage and dispensing of the oxide powder under standard laboratory conditions without unnecessary bulk.
This article is part of Metals, elements & oxides, in Inorganic chemicals.

Questions about Europium(III) oxide, ROTI®METIC 99,995 % (4N5), 5 g, plastic
What is this article?
Europium(III) oxide, ROTI®METIC 99,995 % (4N5), 5 g, plastic is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Metals, elements & oxides, inside Inorganic chemicals, in Lab chemicals.
Metals, elements and oxides are the element itself or its oxide, sold as powder, shot, foil or wire. Purity and particle size are both the specification. A 99 percent powder and a 99.999 percent shot of the same element are different articles. Many are reactive to air or to water.
An inorganic chemical is a salt, an acid or base in solid form, a metal, an oxide, or an element. The waters of hydration are part of the formula: a hydrate and an anhydrous salt are different masses for the same ion. Trace metals matter when the salt will be used in analysis. Nanomaterials add particle size to the specification. Look the substance up on PubChem. Hazard classes are on ECHA, under the CLP Regulation and REACH. Transport of the dangerous ones is explained by the UNECE.
