Figure 4
(a) Phase-colored EBSD map of SnO2 with 50% addition of Co3O4 and Nb2O5 in the ratio for the formation of Co4Nb2O9 phase sintered at 1300°C. Blue lines are (101) TBs in SnO2 grains, whereas red lines indicate epitaxial contacts between SnO2 (blue) and Co4Nb2O9 (brown) with (101)Cst || (110)Crn-t and (010)Cst || (001)Crn-t. The frequency of these contacts is above the uniform misorientation distribution function (MDF) as shown in the histogram below the map. (b) TEM image of the sample with the 10% addition of both oxides in the same ratio shows a SnO2 grain in contact with Co4Nb2O9 particle. Selected area diffraction patterns recorded from both phases disclose epitaxial OR between both phases: ![[[111]_{\rm Cst} (101)_{\rm Cst} \parallel [2{\bar 2}1]_{{\rm Crn}\hbox{-}{\rm t}}]](teximages/yh5020fi16.svg){kind=small} (110)Crn-t. This OR is identical to the epitaxial contacts determined by EBSD. |
