Abstract: | Several different kinds of planar defects have been observed by means of high-resolution electron microscopy in W4Nb26O77, such as disordered intergrowth of WNb12O33 and W3Nb14O44 structural slabs, locally ordered intergrowth with a sequence of AABAAB, two separate microdomains of WNb12O33 and W3Nb14O44 coexisting with W4Nb26O77 and a complicated intergrowth of W4Nb26O77, NNb2O5, W3Nb14O44, and Nb31O77F types of structure. |
