| Abstract: | Different morphologies of BaCO3 crystals with dendritic structure,spinous sphere structure,and spike-,flower-and rod-like structures were prepared with(C2H5)2CO3 and BaCl2.2H2O as raw materials by homogeneous precipitation method.The crystals have been characterized by SEM,FT-IR and XRD,indicating that the different morphology of BaCO3 crystals belongs to the orthorhombic crystal system with uniform distribution and integral shapes.The effect of reaction conditions and the possible formation mechanism on the morphology of BaCO3 crystals have been discussed. |
