The reactive magnesium oxide is an important raw material to prepare high functional fine inorganic material, electronic components, printing ink, adsorbing material of poison gas, etc.
The manufacturing technique of reactive magnesium oxide is the same basically as light magnesium oxide. The mainly difference is the technological condition controlled. The main production methods are: dolomite method, brine ammonia process, and so on. In addition, according to the different requirements for raw material, operational approach and product index, it also can adopt these following techniques, such as vapor phase method, alkoxide hydrolysis, direct precipitation method, collosol gel method, solid phase method, spray pyrolysis and so on.
