  • Hydrogrossular - Wikipedia

    en.wikipedia.org/wiki/Hydrogrossular katoite: 1.5 < x < 3. Hydrogrossular is a garnet variety in which a Si 4+ is missing from a tetrahedral site. Charge balance is maintained by bonding a H + to each of the four oxygens surrounding the vacant site. Hydrogrossular is found in massive crystal habit, sometimes grown in with idocrase.

In the anode area, the ettringite content in the 0.5–5 mm area increased slowly with the exposure time, and the contents of monocarbonate and hemicarbonate decreased ( Fig. 7 c).
