spherical porous basic magnesium carbonate (Mg5(CO3)4(OH)2.4H2O) has been prepared by using ammonium bicarbonate and magnesium chloride hexahydrate as raw materials. A novel CO2 bubble template was constructed to explain the formation of pore structure of porous Mg5(CO3)4(OH)2.4H2O. System pressure was found to be important in controlling the final pore size of spherical porous Mg5(CO3)4(OH)2.4H2O. By the investigation of the particles from pressure-dependent experiments, scanning electron microscopy observations, X-ray diffraction, and Fourier transform infrared spectra were used to follow the reactions and identify the products. The results show that the pore size of spherical porous Mg5(CO3)4(OH)2.4H2O gradually decreased via increasing system pressure.
