| Abstract: | Nanometer calcium carbonate particles were prepared by calciumcarbide residue. Several parameters such as raw materials concentration, carbon dioxide concentration, gas flow rate, reaction temperature, agitating rate, and additive dosage were taken into account. The prepared particles were characterized by TEM, XRD measurement. The result shows that calcium carbonate is calcite, and the average particle size is 50 nm, and the grain size is 30 nm. |
