Alkali-Activated Metakaolins: Mineral Chemistry and Quantitative Mineral Composition [PDF]
Minerals, 2022 The reaction products resulting from the alkali-activation of metakaolin are impacted by the composition of the initial kaolin, and amount of alkali-activated kaolinite and water. The present study focused on analyzing these parameters on the metakaolins calcined at 800 °C from three kaolins, and the metakaolins’ alkali activation for 2, 3 and 28 days.

Aquamarine from Massangana batholith, Rondônia State: mineral chemistry and fluid inclusion data
REM: International Engineering Journal, 2020 Beryl is usually found in granite-pegmatite systems. The addition of chromophore elements (V, Cr, Mn, Fe) into the crystalline structure favors color changes in beryl and thus generates some of the world’s expensive gems such as emerald, morganite ...
