Dead burned magnesium oxide has been calcined at temperatures ranging from 1500ºC – 2000ºC in a high temperature shaft kiln yielding a material with very little reactivity. MagChem® P98 products are high purity, dead burned magnesium oxides with high density and low reactivity. These products are well suited in the manufacture of magnesia carbon refractory bricks, monolithic gunning refractories, specialty refractory applications (precast shapes and castables), and miscellaneous ceramics.

Martin Marietta Magnesia Specialties also offers sized and milled grades of MagChem P98, which are used in a variety of applications such as LCD glass, oil & gas drilling fluids and cements, ceramics, and many other specialty applications.
