Description
Tantalum(V) oxide ROTI®METIC 99,99 % (4N) is a high-purity inorganic oxide with the empirical formula Ta₂O₅ and CAS number 1314-61-0. It has a molar mass of 441,89 g/mol and a density of approximately 8,24 g/cm³, making it suitable for analytical work, materials research, and inorganic synthesis where tightly controlled impurity levels matter. This 4N grade is Physical constants and identity data align with standard reference values for Ta₂O₅, aiding method development, thin-film and ceramic studies, and electronic materials projects. The ROTI®METIC specification from manufacturer Carl ROTH denotes 99,99 % purity for applications that demand a well-defined tantalum oxide feedstock. EG number 215-238-2 supports clear regulatory and inventory documentation. Compact HDPE packaging helps protect the solid during storage and transfer on the bench. Overall, the combination of stated purity, known molar mass and density, and a practical pack size makes this tantalum(V) oxide a reliable choice for research and quality-control laboratories needing consistent high-purity oxide material.

Questions about Tantalum(V) oxide, ROTI®METIC 99,99 % (4N), 5 g, HDPE
What is this article?
Tantalum(V) oxide, ROTI®METIC 99,99 % (4N), 5 g, HDPE 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?
The category is Inorganic chemicals. The sub-category is Metals, elements & oxides. The catalogue is Lab chemicals.
Shelves beside this one are Inorganic salts and Nanomaterials & quantum dots.
What should I check before I order?
The technical information on this page is the manufacturer's sheet. Read that, not a rewritten specification.
When this page shows a safety data sheet, use that manufacturer file. Hazard text does not belong in the sales description. For a pack size, a grade or a certificate that is not on the page, send a quote request or contact the team.
