      abstract     = {Two calcined products of Li6.4Fe0.2La3Zr2O12 can be
                      synthesized via the solid state method and the sol gel
                      method. Inhomogeneities of the iron distribution in the
                      powder for the solid state method lead to a combination of
                      cubic and tetragonal structure. By using the sol gel method
                      the homogeneity can significantly been increased resulting
                      in the desired pure phase cubic structured powders in
                      I4¯3d. By in situ dilatometer measurements the
                      densification process can be comprehended for the first time
                      for garnet type materials. The density can be significantly
                      increased by the usage of the sol gel synthesis compared to
                      the solid state synthesis with short sintering times of 2 h
                      delivering pure phase pellets for both synthesis methods.
                      Electrical impedance measurements revealed clearly divided
                      semicircles for the bulk and the grain boundary contribution
                      for the solid state synthesis, while the sol gel synthesis
                      showed only one semicircle from the bulk contribution due to
                      a large crystallite size. The total ionic conductivity for
                      the pellet synthesized via the sol gel method is 1.82 mS/cm
                      at 25°C which is the fastest found so far for garnet type
                      or garnet related materials.},
