High angle [001] twist boundaries in platelet colonies of BiSrCaCuO (2223) superconductor.
The microstructure of BiPbSrCaCuO (2223) ceramic was studied by polarised light microscopy and the etch-pits technique. The high-angle twist grain boundaries in the platelet colonies were confirmed to be [001] coincidence type twisted boundaries or rotation twin boundaries with the (001) twinning plane.
