A white to gray mineral composed of [[magnesium hydroxide]]. Brucite was named for Archibald Bruce, an American mineralogist in the late 18th and early 19th centuries. It occurs naturally in deposits, often with [[serpentine]] and [[dolomite]], in Italy (Teulada), Sweden (Jakobsberg, Filipstad, Nordmark), Canada, and the U.S. (Nevada, New Jersey, Pennsylvania, Texas). The soft mineral can be transparent to translucent with a pearly luster. Brucite is used as a refractory material as well as for a source of [[magnesium]] metal and [[magnesia]].

Brucite

Description

Brucite

A white to gray mineral composed of Magnesium hydroxide. Brucite was named for Archibald Bruce, an American mineralogist in the late 18th and early 19th centuries. It occurs naturally in deposits, often with Serpentine and Dolomite, in Italy (Teulada), Sweden (Jakobsberg, Filipstad, Nordmark), Canada, and the U.S. (Nevada, New Jersey, Pennsylvania, Texas). The soft mineral can be transparent to translucent with a pearly luster. Brucite is used as a refractory material as well as for a source of Magnesium metal and Magnesia.
