  • Katoite: Mineral information, data and localities.

    www.mindat.org/min-2167.html In end-member katoite, the replacement is complete (so x = 3). Previously, the mineral "hibschite" (no longer an IMA-approved species) was considered an intermediate member of the grossular-katoite series, and was defined as Ca 3 Al 2 (SiO 4 ) 3-x (OH) 4x , where x = 0.2-1.5; compositions where x < 0.2 were still considered grossular, whereas ...

    www.minerals.net/mineral/katoite.aspx The mineral Katoite is the same as Hibschite, but contains less hydroxyl replacing the silicate (In Katoite, x is 0.2 to 1.5). Hibschite and Katoite are white to light yellow, and only occur in tiny crystals, which may be packed together very densely. Katoite and Hibschite are called Hydrogarnets, or Garnets

  • Hydrogrossular (Katoite): Vibrational, Crystal-Chemical ...

    ui.adsabs.harvard.edu/abs/2011AGUFMDI21A2054D/abstract Thus, we studied the low temperature IR spectra and measured the heat capacity of katoite in order to investigate its vibrational, crystal-chemical and thermophysical properties. Katoite was synthesized hydrothermally in Au capsules at 250 °C and 3 kb water pressure. X-ray powder measurements show that about 98-99% katoite was obtained.

  • Hydrogrossular - Wikipedia

    en.wikipedia.org/wiki/Hydrogrossular Hydrogrossular is a calcium aluminium garnet series (formula: Ca 3 Al 2 (SiO 4) 3−x (OH) 4x, with hydroxide (OH) partially replacing silica (SiO 4)).The endmembers of the hydrogarnet family (grossular, hibschite, and katoite) depend on the degree of substitution (x):grossular: x = 0 hibschite: 0.2 < x < 1.5 katoite: 1.5 < x < 3. Hydrogrossular is a garnet variety in which a Si 4+ is missing ...
