Applications:
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 .
It is used as a principal ingredient in construction materials used for fireproofing.
It is used as an insulator in devices that exhibit the effect.
An industrial use of magnesium oxide is in leather processing, as a basifying agent on chrome tanning process
