Magnesium Oxide

Applications:

Magnesium oxide is used in various applications in the refractory industry, agricultural industry, chemical industry, construction industry, environmental industry, and other industrial applications. Its main use is as refractory material, but it is also used extensively as an electrical insulator in tubular construction heating elements as in electric stove and cook top heating elements. Magnesium oxide is also used in the production of cement for the construction industry, and it is a principal fireproofing ingredient in construction materials. It is also used in the manufacturing of commercial plant fertilizer and animal feed. Magnesium oxide is used extensively in the soil and groundwater remediation, wastewater treatment, drinking water treatment, air emissions treatment, and waste treatment industries for its acid buffering capacity and related effectiveness in stabilizing dissolved heavy metal species. Magnesium Oxide also has niche uses like as a reagent in the installation of the carboxybenzyl (Cbz) group using benzyl chloroformate in EtOAc for the N-protection of amines and amides and  is used as an oxide barrier in spin-tunneling devices. It is also historically used as a reference white color in colorimetry, owing to its good diffusing and reflectivity properties.
