APPLICATIONS

Magnesium Hydroxide is a white powder; specific gravity 2.36; , very slightly soluble in water;. decomposing at 350 C. It occurs naturally as the mineral called brucite or is prepared by reacting magnesium sulphate or chloride with sodium hydroxide. It is used in the refining of sugar, in extraction of magnesium metal, in the processing of uranium, and in the sulfite wood pulp process. It is an inert filler, flame retardant and smoke suppressant for plastics, synthetic rubber, reinforced polyesters, phenolics, and urethane foam. Magnesium hydroxide releases its 31% water when heated to above 325 C, which cools the product below flash point to reduce fire occurance. Medicinally it, in the form of a mixture (milk of magnesia), is also used as an antacid and as a osmotic laxative.
