Abstract

A transmission electron microscopy (TEM) study on the real internal structure of synthetic hematite sample was conducted. The samples were prepared by dissolving ferric chloride hexahydrate (FeCl3 · 6H2O) in water at room temperature, resulting in a clear 0.02 M solution of yellow color. The results show that the ideal hematite lattice can be seen at the lower right corner of the image, the rest of the image shows a deviating periodicity. A convergent-beam electron diffraction (CBED) pattern of natural hematite shows remarkable differences compared to those of the synthetic samples. The symmetry of the synthetic particle of own production matches the quality of the natural sample in the area near the sample edge, which corresponds to the lower right of the image.
