Bruce +‎ -ite after its discoverer, American mineralogist Archibald Bruce.


  • The valley's also rich in brucite, and there's at least some gold.

    Susan and Sharon's Excellent Adventure

  • The silicate and brucite layers share oxygen atoms which would normally be separated by distances of 0.305 nm in the silicate layer and 0.342 nm in the brucite layer.

    Geology of asbestos

  • Free brucite, present as contaminant in the fibers, also contributes to the pH increase.

    Geology of asbestos

  • In the case of chrysotile, an octahedral brucite layer having the formula (Mg6O4 (OH) 4) -4 is intercalated between each silicate tetrahedra sheet.

    Geology of asbestos

  • In the case of chrysotile, the crystalline structure is stable up to approximately 550° C (depending on the heating period), where the dehydroxylation of the brucite layer begins.

    Geology of asbestos

  • In the octahedral layer (brucite), magnesium can be substituted by several divalent ions, Fe+2, Mn +2, or Ni+2.

    Geology of asbestos

  • In the case of chrysotile fibers (in a given amount of water), the brucite layer will, fairly rapidly, dissolve in part, with concomitant increase in the pH of the solution.

    Geology of asbestos

  • In contact with solutions of mineral acids, organic acids, or magnesium complexing agents, the rate of dissolution of the brucite layers is increased.

    Geology of asbestos

  • A native magnesia of New Jersey, it was named after him: “brucite.”

    American Connections

  • It dissolves in acid readily with but little effervescence, which little, however, distinguishes it from brucite, which it sometimes resembles and which has a much lower-specific gravity when pure.
