Specific twin junctions in doped zirconia.
The effect of different dopant cations on the phase transformations of the initially stabilized supersaturated tetragonal ZrO(2) phase during various heat treatments has been studied. The obtained fraction of monoclinic grains develop twinned structures, but there is still a lack of information about the character of grain boundaries formed in doped monoclinic solid solutions. The inspection of particular selected-area electron diffraction patterns provides an alternative method with respect to high-resolution electron microscopy or electron back-scattered diffraction for characterizing different twin junctions in various doped zirconia systems. The classification of these special twins is based on the coincidence site lattice concept.
