Figure 3From: Surface Modification and Planar Defects of Calcium Carbonates by Magnetic Water TreatmentTEM a BFI, b SAED pattern (Z = [211]) of a submicron-sized magnetite particle with well-developed () face and {111} facets, c EDX spectrum indicating negligible impurities for the magnetite. The Cu counts were from the copper grids holding the specimen. The TEM sample was prepared from the same specimen as Fig. 1 Back to article page
