Description

Molecular Formula:MgO 

Molar mass:*0.***4 g/mol

CAS No.: ********4

Product Description：
Magnesium oxide, or magnesia, is a white solid mineral that occurs naturally as periclase and is a source of magnesium (see also oxide). It has an empirical formula of MgO. It is formed by an ionic bond between one magnesium and one oxygen atom. Magnesium oxide is easily made by burning magnesium ribbon which oxidizes in a bright white light, resulting in a powder. It is hygroscopic in nature and care must be taken to protect it from moisture. Magnesium hydroxide forms in the presence of water (MgO + H2O → Mg(OH)2), but it can be reversed by heating it to separate moisture.

Applications:
It is used by many libraries for preserving books by reacting with ambient moisture to dry the book storage areas. 
It is used as one of the raw materials for making cement in dry process plants; specifically Portland cement. If too much is added, the cement may be expansive. 
It is used as an insulator in industrial cables. 
It is used as a basic refractory material for crucibles. 
It is used as a principal ingredient in construction materials used for fireproofing. 
It is used by rock climbers as a way to reduce sweat and moisture on hands and holds. 
It is used as a reference white color in colorimetry, owing to its good diffusing and reflectivity properties. It may be smoked onto the surface of an opaque material to form an integrating sphere.
