[mag′nē·zē·əm hī′dräk‚sīd]
(inorganic chemistry)
Mg(OH)2 A white powder, very slightly soluble in water, decomposing at 350°C; used as an intermediate in extraction of magnesium metal, and as a reagent in the sulfite wood pulp process. Also known as magnesium hydrate.

magnesium hydroxide

A white powder which is slightly soluble in water; in dolomitic-type limes used in plaster, its presence helps the lime to spread more easily.
