Precipitation of mesoporous nanosized calcium carbonate
Mesoporous calcium carbonate particles of nanosized dimensions were produced by bubbling CO2 gas through a suspension of calcium hydroxide. The precipitates were formed through initial generation of an amorphous precursor phase on the surface of Ca(OH)2 particles, its transformation into nanosized crystalline calcite and finally by aggregation into nanostructural mesoporous calcite particles. The structure and morphology of the product were investigated by using scanning and transmission electron microscopy, X-ray diffraction, specific surface area and porosity measurements. The mean particle diameter was found to be approximately 150 nm with the pore size of about 50 nm.
