  • Halloysite - Wikipedia

    Halloysite is an aluminosilicate clay mineral with the empirical formula Al 2 Si 2 O 5 (OH) 4.Its main constituents are aluminium (20.90%), silicon (21.76%) and hydrogen (1.56%). Halloysite typically forms by hydrothermal alteration of alumino-silicate minerals. It can occur intermixed with dickite, kaolinite, montmorillonite and other clay minerals. X-ray diffraction studies are required for ...
