| Abstract: |
| Magnesium oxide is an important inorganic chemical raw material with great demand and is the raw material for preparing high value-added magnesium products. One of its sources is obtained by calcining magnesite at high temperature. High activity magnesia products were prepared by optimizing calcination process, i.e., controlling particle size of magnesite particles, calcination mode, with/without additives addition, controlling impurity content of magnesite internal components, and application of new calcination process. The preparation and activity detection of magnesia are inseparable. Calcination modes of magnesite and activity detection of magnesia were summarized. Prospects and suggestions for improvement of process were put forward. |
