Description
Copper powder is a high-purity elemental metal powder specified at min. 99,7 %, p.a., with particle size below 63 µm. It carries CAS number 7440-50-8 and empirical formula Cu, a molar mass of 63,54 g/mol and a density of 8,96 g/cm³. The boiling point is 2580 °C. This analytical-grade fine powder is suited to laboratory work in inorganic chemistry, catalysis screening, materials research and sample preparation where controlled copper metal feedstock is required. The sub-63 µm fraction provides a large surface area for reactions and blending. EG nr. 231-159-6 aids regulatory and inventory identification. Physical constants such as density and molar mass support stoichiometric calculations and formulation work. Handle finely divided copper powders with standard precautions against dust dispersion and oxidation during weighing and transfer.

Questions about Copper powder, min. 99,7 %, p.a., <63 µm, 100 g, plastic
What is this article?
Copper powder, min. 99,7 %, p.a., <63 µm, 100 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.
