Method for producing dead burned magnesia and products obtainable thereby. The invention relates to magnesium oxides and methods for producing them. Provided is a method for producing a sintered, high density, dead burned magnesia (DBM) from an aqueous slurry of magnesium hydroxide or a mixed magnesium hydroxide / magnesium oxide slurry,characterized inthat Ti0 2 and graphite are added to the aqueous slurry each in amount of 0.05 to 0.5 percent, preferably 0.1 to 0.3 percent, by weight of the magnesium hydroxide. Also provided is a sintered, high density, dead burned magnesia having a MgO content of 97-99 wt%, a density of at least 3.50 g/cm 3 and a crystal size of at least 90 microns. |
