Darstellung und Reaktionen von Psilomelan (Romanéchit) Ba2Mn15O30∙4H2O
Psilomelane Ba2Mn15O30∙4H2O was synthesized under hydrothermal conditions from Ba-7Å-phyllomanganate(IV) in BaCl2 solution. The topotactic reaction transforms the initial layer lattice into needles with tunnels twice the size of hollandite type tunnels. These are filled with unexchangeable Ba2+ ion...
