Abstract A novel and simple method for preparing tubular structure agglomerates of calcium carbonate (CC‐tube) is described. 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 sodium carbonate aqueous solutions on the morphology and phase structure of the as‐obtained samples were investigated. The CC‐tube growth was prevented with the increase of reactant concentration from 0.5 to 1.0 mol·L −1 . Compared with Na 2 CO 3 aqueous solution, it is favourable to grow calcite crystals in CaCl 2 aqueous solution. The products were characterized by X‐ray diffraction, Fourier transform infrared spectroscopy and scanning electron‐ microscopy.
