Magnesium Oxide, it is a versatile mineral that when used as part of a cement mixture and cast into thin cement panels under proper curing procedures and practices can be used in residential and commercial building construction.   MgO boards are used in place of traditional gypsum drywall as well and ceiling covering material and sheathing. 

For magnesia board production, high reactivity is requested.  Richase provide the high reactivity with high LOI and low CaO magnesium oxide, which is special for magnesium board.
