Manganese hollandite-type

Another example of the hollandite-type manganese oxides is Ki.5(H30)x MngOi6 [131, 132], where the HsO groups occupy part of the 1/4 vacant sites in the tunnels, not occupied by potassium ions. These groups intercalate into the structure during a hydrothermal synthesis. From susceptibility measurements, three phase transitions were observed [131, 132] at Ti = 180-250 K, Tj = 52 K, and T3 =... [Pg.811]

Hollandite- or cryptomelane-type manganese oxides have a one-dimensional tunnel structure comprised of tunnels with an almost quadratic cross section... [Pg.232]
