Twinning in SnO₂-based ceramics doped with CoO- and Nb₂O₅: morphology of multiple twins revealed by electron backscatter diffraction.

ABSTRACT: Electron backscatter diffraction (EBSD) was used for the analysis of multiple cyclic twins in cassiterite (SnO₂), which form during sintering of SnO₂ with small additions of CoO and Nb₂O₅. Grain misorientation analysis has shown that about one third of all grains contain {101} twin boundaries (TBs). The majority of these grains are contact twins, whereas a small fraction of grains are multiple, mainly cyclic twins. A procedure was developed in MTEX [Bachmann, Hielscher & Schaeben (2010). Solid State Phenom. 160, 63-88] for automated identification of crystallographically different types of cyclic twins and found two main types: coplanar twins composed of three or four domains with a common [010] axis and alternating twins composed of three to sev
