There are many ways that magnesium oxide can be formed. One way in which magnesium oxide is made is the burning of magnesium ribbon in air. This creates a white smoke that contains mostly fine particles of magnesium oxide. It then forms into a white powder consisting of about 90 percent magnesium oxide and 10 percent magnesium nitride, since both the oxygen and the nitrogen in the air will react with the magnesium.<ref>Ophardt, Charles E.

Magnesium oxide can also result from the breaking down of magnesium carbonate or magnesium hydroxide. Both will create magnesium oxide in a reaction that occurs when they are in the presence of heat.<ref name=webelements/> Most magnesium oxide is obtained by processing materials like magnesite, a form of magnesium carbonate, and brine, which can contain magnesium chloride.<ref> [http://www.magnesiaspecialties.com/students.htm Basic Facts about Magnesium Oxide and Magnesium Hydroxide] ''Martin Marietta Magnesia Specialties''.

Periclase is a mineral that can usually be located in dolomitic limestone. | Magnesium oxide can also result from the breaking down of magnesium carbonate or magnesium hydroxide.
