Description
Indium powder is an elemental metal reagent offered at a minimum of 99 % in p.a. quality for analytical and general laboratory use. Identified by CAS number 7440-74-6 and EG number 231-180-0, it has the empirical formula In, a molar mass of 114,82 g/mol, a density of 7,29 g/cm³ and a boiling point of 2072 °C. The material is supplied as a fine powder Indium powder is applied in inorganic chemistry, materials science and laboratory work that requires a defined elemental indium source for standards preparation, alloy-related studies or specialised reactions. Physical data and the stated purity support reproducible handling when working with group 13 metals under routine laboratory conditions. This grade from manufacturer Carl ROTH fits chemical catalogues focused on pure elements and inorganic reagents, giving laboratories a compact pack size for method development, teaching experiments and small-scale preparative work without excess inventory.
This article is part of Metals, elements & oxides, in Inorganic chemicals.

Questions about Indium powder, min. 99 %, p.a, 5 g, glass
What is this article?
Indium powder, min. 99 %, p.a, 5 g, glass 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.
