Abstract
A process for the preparation of active magnesium oxide by mixing of hydrated magnesium carbonate with magnesium oxide and/or magnesium hydroxide and thermal treatment of mixture with heating rate of 40-80 °С. Additives of boron oxide and/or chrome oxide in quantity of 0.3-1 % from mass of hydrated magnesium carbonate are additionally added to the mixture, the mixture before the thermal treatment is given to mechanochemical activation, after which it is granulated, and the thermal treatment is carried out in interval of temperatures 400-600 °С in moving bed.
