Description
Magnesium powder is a fine elemental metal powder with a minimum purity of 99,8 % and a minimum particle size of 75 µm. It is identified by CAS number 7439-95-4 and empirical formula Mg, with a molar mass of 24,31 g/mol and a density of 1,75 g/cm³. The boiling point is 1095 °C. This grade supports laboratory applications that require reactive magnesium metal in powdered form, including organic synthesis, Grignard-related preparations where particle size is specified, and materials or metallurgical test work. Defined purity and particle-size limits help ensure consistent reactivity and handling characteristics. EG nr. 231-104-6 supports substance identification in chemical inventories. As with other finely divided reactive metals, appropriate laboratory controls for ignition and moisture sensitivity should be observed during storage and use.
This article is part of Metals, elements & oxides, in Inorganic chemicals.

Questions about Magnesium Powder, min. 99,8 %, min. 75 µm, 100 g, plastic
What is this article?
Magnesium Powder, min. 99,8 %, min. 75 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.
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.
