A process using plentiful and inexpensive caustic calcined magnesia (CCM; main component is MgO) to prepare lamellar MH of high purity described. The begins with the reaction MgO in CCM NH4NO3 at ∼100 °C produce ammonia gas Mg(NO3)2 solution subsequent filtration remove impurities (e.g., SiO2). Then, obtained introduced into precipitate NH4NO3. After separated by filtration, filtrate containing returned initial step. overall this hydration MH. Therefore, called apparent-hydration method....
Aqua ammonia (AA) is frequently used to precipitate various metal hydroxide or oxide particles. Here, we replace AA with gaseous (GA) Mg(OH)2 particles in MgCl2 aqueous solution under mild conditions. The results show that GA can give a higher consistency the growth of although both and essentially produce by reaction Mg2+ OH−. This work provides suggest using as precipitant.
