    Abstract. On calcination of basic magnesium carbonate at 20-800 C, an induction period was observed in the initial stage of thermal decomposition. At the decomposition degree higher than 20% of the weight loss, the specific surface area varied in proportion with the decomposition degree, which points to equal rates of gas liberation and recrystallization of intermediate products into an active oxide

    Commercially available magnesium oxide (magnesia or MgO) is produced mainly by two methods, the first via the calcination or heating of magnesite, a naturally occurring mineral of magnesium carbonate. The second method involves the precipitation of magnesium hydroxide from seawater, or magnesium-rich brines, using lime or dolime; the magnesium hydroxide then being calcined to form magnesium
