Abstract  

The crystal growth morphologies of manganese carbohydrazide perchlorate, iron carbohydrazide perchlorate, cobalt carbohydrazide perchlorate, nickel carbohydrazide perchlorate and cadmium carbohydrazide perchlorate were investigated by Bravais-Freidel-Donnay-Harker (BFDH) and growth morphology method. The results show that the crystal morphologies of them are close to oblong block shapes, and the growth on (101)and (002) faces are the most important growth direction because of the minimum relative growth rates. According to the cleaved main growth faces, it can be inferred that crystal-control reagents with the active hydrogen atoms in the functional groups can effectively control the crystal morphology for them. In addition, the experimental morphologies of them were synthesized and observed by a coldfield-emission scanning electron microscope. It is concluded that AE model are nearer to experimental morphology, and more reliable to predict crystal morphologies for carbohydrazide perchlorates.
