Description
Silver powder is a high-purity elemental metal powder with a minimum assay of 99,9 % and a typical particle size of approximately 30 µm. Identity data include CAS number 7440-22-4, EG number 231-131-3 and the empirical formula Ag. Reference physical properties list a density of 10,5 g/cm³ and a boiling point of 2212 °C, giving a clear characterisation profile for laboratory planning and documentation. The product is packed as 1 g in glass, suited to small-scale experimental needs. Typical uses span materials research, analytical sample preparation and specialised synthesis that benefits from finely divided silver rather than foil or bulk metal. Available from manufacturer Carl ROTH, this grade supplies a practical quantity for method development, reference work and exploratory solid-state or surface investigations. Apply standard laboratory controls for fine metal powders and review the safety data sheet before handling. With defined purity, particle size and documented chemical identity, the powder supports reproducible workflows wherever elemental silver in particulate form is required.

Questions about Silver powder, min. 99,9 %, ca. 30 µm
What is this article?
Silver powder, min. 99,9 %, ca. 30 µm 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?
