Description
Lanthanum(III) oxide is a high-purity rare-earth oxide with the empirical formula La₂O₃, CAS number 1312-81-8 and EG number 215-200-5. Offered as ROTI®REMETIC material at 99,999 % purity, it presents a molar mass of 325,81 g/mol and a density of 6,51 g/cm³, together with a boiling point of 4200 °C. from manufacturer Carl ROTH supplies a practical quantity for materials science, catalysis research and specialty inorganic synthesis. Lanthanum(III) oxide serves as a precursor for mixed-metal oxides, optical materials, ceramic formulations and catalytic systems where controlled lanthanum content is essential. Its elevated purity grade supports applications that demand minimal metallic impurities, including advanced ceramics, phosphor-related studies and thin-film or solid-state investigations. Laboratories value the combination of well-documented physical constants and the ROTI®REMETIC specification when preparing standards, doping mixtures or high-temperature reaction feeds. Within chemical catalogues spanning rare-earth compounds, this oxide remains a foundational reagent for exploratory research and process-oriented development requiring reliable lanthanum sources.

Questions about Lanthanum(III) oxide, ROTI®REMETIC 99,999 %, 25 g, plastic
What is this article?
Lanthanum(III) oxide, ROTI®REMETIC 99,999 %, 25 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.
