Description

Bulk density: 4-8 lb./cu.ft. | CAS: 1309-48-4 | MgO | 40.30 g/mol

Magnesium oxide is used as a laboratory reagent and an insulator in industrial cables. It acts as a reference material for calorimetry. It is widely used as a basic refractory material for crucibles, a protective coating in plasma displays, an oxide barrier in spin-tunneling devices, an optical material, a component of tubular construction in heating elements, and also in libraries for preserving books. Magnesium oxide microspheres used in enrichment method of polycyclic aromatic hydrocarbons.
