摘要Different morphology of BaCO3 crystals with dendritic structure, spinous spheres structure, spike-, flower- and rod-like structures were prepared with (C2H5)2CO3 and BaCl2·H2O as raw materials by homogeneous precipitation method. The crystals have been characterized by SEM, FT-IR and XRD, indicate that the different morphology of BaCO3 crystals belong 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.
