Magnesium oxide may be acclimated for altered reasons. Some humans use it as an acrid to abate heartburn, acerb stomach, or acerbic indigestion. Magnesium oxide aswell may be acclimated as a laxative for short-term, accelerated elimination of the bowel (before surgery, for example). It should not be acclimated repeatedly. Magnesium oxide aswell is acclimated as a comestible supplement if the bulk of magnesium in the diet is not enough. Magnesium oxide is accessible after a prescription.
Magnesium oxide is produced by the calcination of magnesium carbonate or magnesium hydroxide or by the analysis of magnesium chloride with adhesive followed by heat.Calcining at altered temperatures produces magnesium oxide of altered reactivity. High temperatures 1500 – 2000 °C abate the accessible apparent breadth and produces dead-burned (often alleged asleep burnt) magnesia, an apathetic anatomy acclimated as a refractory. Calcining temperatures 1000 – 1500 °C aftermath hard-burned magnesia which has bound acuteness and calcining at lower temperature, (700-1000 °C) produces light-burned magnesia, a acknowledging form, aswell accepted as abrasive calcined magnesia. Although some atomization of the carbonate to oxide occurs at temperatures beneath 700 °C, this appears rapidly capricious due to assimilation of carbon dioxide from the air.
