The basic problem associated with the production and use of this type of refractories is inherent tendency to hydration of calcined dolomite. One of the methods to overcome this problem is to increase the amount of magnesia in doloma. This study focuses on the use of Iranian dolomite to produce magnesia –doloma (mag-dol) refractory with high resistance to hydration and corrosion. It was found that addition of 20wt% magnesite to dolomite would result in capsulating of CaO by MgO that protects doloma from further hydration Dolomite, Magnesite, Mag-dol, Refractory, Hydration, Corrosion 0 0 http://ijmse.iust.ac.ir/browse.php?a_code=A-10-3-127&slc_lang=en&sid=1 A.
