ISO 9001:2015 & ISO 14001:2015 zertifiziert · Lieferant für Laboratorien und Industrie seit 2000 · Analysezertifikat (Certificate of Analysis, CoA) für jede Charge
Magnesium powder (particle size <75 µm, CAS 7439-95-4) is a highly reactive, silvery-white metal used in pyrotechnics, incendiary devices, and as a reducing agent in chemical synthesis. It also serves as an alloying element in aluminum and zinc alloys to enhance strength and corrosion resistance. This fine magnesium powder has a molecular weight of 24.31 g/mol and must be stored in a dry, inert atmosphere to prevent oxidation. It carries a **Danger** signal word due to its flammability and reactivity with water and air. Handling requires proper PPE and fire safety precautions. Molekula supplies Magnesium powder from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
