Description
Samarium(III) oxide is a high-purity rare-earth oxide supplied as ROTI®REMETIC 99,95 % for demanding laboratory and materials applications. Identified by CAS number 12060-58-1 and empirical formula Sm₂O₃, it has a molar mass of 348,72 g/mol and a density of 8,34 g/cm³. These values support stoichiometric calculations, formulation work, and solid-state chemistry where samarium content must be tightly controlled. The product is EG number 235-043-6 anchors regulatory and catalogue identification. Available from manufacturer Carl ROTH in the ROTI®REMETIC range, this oxide provides a clearly specified Sm₂O₃ source for laboratories that require elevated purity without unnecessary bulk. Density and molar-mass data facilitate weighing and conversion steps in synthesis protocols, while the compact pack size helps manage inventory for specialised rare-earth workflows in academic and industrial research settings.

Questions about Samarium(III) oxide, ROTI®REMETIC 99,95 %, 5 g, plastic
What is this article?
Samarium(III) oxide, ROTI®REMETIC 99,95 %, 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.
Which category should I open next?
