A chemical compound having the formula MgO which appears under the form of a noncombustible, white, alkaline powder, either light or heavy depending upon whether it is prepared by heating magnesium carbonate or the basic magnesium carbonate, is slightly soluble in water, soluble in acids and ammonium salt solutions, insoluble in alcohol, combines with water to form magnesium hydroxide, occurs naturally as the mineral periclase, is derived(1) by calcining magnesium carbonate or magnesium hydroxide,(2) by treating magnesium chloride with lime and heating or by heating it in air,(3) from seawater via the hydroxide, and is used as an inorganic rubber accelerator, a polycrystalline ceramic for aircraft windshields, in refractories, especially for steel furnace linings, for electrical insulation, in fertilizers, oxychloride and oxysulfate cements, paper manufacture, pharmaceuticals and cosmetics, semiconductors, for the removal of sulfur dioxide from stack gases and as a feed additive and in the food industry(mainly for the deacidification of butter, cooa, and some canned or frozen foods).  7, fiche 1, Anglais, - magnesium%20oxide

Enhanced well productivity potential from a new high-density reservoir drilling fluid.... The new fluid system... derives its viscosity solely from an interaction between a specially modified starch(DFS) and an inorganic magnesium compound(HRMgO) [=highly reactive magnesium oxide].  3, fiche 2, Anglais, - inorganic%20magnesium%20compound

Dietary Mg [magnesium] supplementation using inorganic Mg sources such as MgSO₄ and MgCl₂ have... been shown to improve meat quality. Studies comparing the influence of organic and inorganic magnesium compounds on meat quality indicate that the improvements in muscle colour, drip loss, and the reductions in the incidence of PSE [pale, soft and exudative pork] were greater with organic magnesium compounds such as magnesium aspartate and magnesium Bioplex.  4, fiche 2, Anglais, - inorganic%20magnesium%20compound
