Transmission electro n microscopy (TEM) was utilized to characterize the shape and size of products a s-prepared, as well as electron diffraction (ED) pattern was obtained for desi gnated nanorods (wires). It is revealed that ù0 (molar ratio of water to surfa ctant),reactants concentration and aging time play an important role in the form ation of different morphologies and size of synthesized CaSO4 nanocrystal.展开更多
