摘要

A novel and simple method for preparing tubular structure agglomerates of calcium carbonate (CC-tube) is de-scribed. Calcium chloride and sodium carbonate aqueous solutions were used as reactants separated by a collodion film (a nitrocellulose material) in aqueous solution. The effects of the concentrations of calcium chloride and so-dium carbonate aqueous solutions on the morphology and phase structure of the as-obtained samples were investi-Compared with Na2CO3 aqueous solution, it is favourable to grow calcite crystals in CaCl2 aqueous solution. The products were characterized by X-ray diffraction, Fourier transform infrared spectroscopy and scanning electron-microscopy.
