Magnesium oxide Wikipedia

Magnesium oxide (Mg O), or magnesia, is a white hygroscopic solid mineral that occurs naturally as periclase and is a source of magnesium (see also oxide). It has an empirical formula of Mg O and consists of a lattice of Mg 2+ ions and O 2− ions held together by ionic bonding .

Process for the production of dead burned refractory magnesia

Jan 06, 1981 · The magnesium hydroxide filter cake obtained by pressure filtration can be directly dead burned to refractory magnesia. This process has the disadvantage of yielding granular dead burned magnesia having a density of only about 3.2 to about 3.35 grams per cubic centimeter (g/cc), depending upon the impurities in the initial starting material.
