Description
Sheets of gold, 22 carat are thin gold leaf sheets supplied as a block of 25 sheets measuring 80 × 80 mm each. Identified by CAS number 7440-57-5 and EG number 231-165-9, this elemental gold material exhibits a density of 19,3 g/cm³ and a boiling point of 2800 °C. The 22-carat grade is suited to laboratory, analytical and specialised technical applications where workable thin gold sheets are required. Available from manufacturer Carl ROTH as a practical 25-sheet block, the product supports controlled handling and precise portioning in research and technical workflows. These gold sheets provide a consistent format for surface studies, sample preparation and other uses that benefit from thin metallic gold layers. The pack of twenty-five individual sheets aids inventory management and repeatable experimental setups across multiple procedures. Density and boiling data correspond to the established physical properties of gold, helping laboratories select an appropriate metallic form. Defined sheet dimensions of 80 × 80 mm further simplify cutting, weighing and application steps in day-to-day laboratory practice.
This article is part of Metals, elements & oxides, in Inorganic chemicals.

Questions about Sheets of gold, 22 carat, block of 25 sheets 80 x 80 mm, 25 sheet(s)
What is this article?
Sheets of gold, 22 carat, block of 25 sheets 80 x 80 mm, 25 sheet(s) 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?
