초록
We investigated the ultrastructure of clay minerals of Boryeong mud powder. Observation of the mud powder sample using a low-magnification scanning electron microscope showed that the powder particles were uniformly dispersed in a relatively homogeneous state, and the relatively large particles were observed in the form of crystals. Using the scanning electron microscope at high magnification of the mud powder, most of the clay mineral particles were in the form of thin plates or lobes, and some trace particles in the shape of nanometer-sized columns were observed. The crystalline mineral particles, which are relatively larger than other mineral particles, measured from 38㎛ to approximately 45㎛ in length, and had a very smooth and flat surface. These crystalline clay minerals appeared in the form of rectangles, ovals, and diamonds. In addition to the particles observed as such large crystals, most of the mineral particles measured had a major axis diameter under 15㎛.
