-
In contact with solutions of mineral acids, organic acids, or magnesium complexing agents, the rate of dissolution of the brucite layers is increased.
-
In the case of chrysotile, an octahedral brucite layer having the formula (Mg6O4 (OH) 4) -4 is intercalated between each silicate tetrahedra sheet.
-
A native magnesia of New Jersey, it was named after him: “brucite.”
-
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.
-
Free brucite, present as contaminant in the fibers, also contributes to the pH increase.
-
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.
-
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.
-
In the octahedral layer (brucite), magnesium can be substituted by several divalent ions, Fe+2, Mn +2, or Ni+2.
