SYNTHESIS OF ULTRAFINE CALCIUM CARBONATE WITH VARIOUS SHAPES

摘要

In this paper, we have synthesized the ulirafine chain-like CaCO_3 with nanometer particle size, spindle, cubic and vaterile CaCO_3 of micrometer and have investigated their crystal structures as well as their physical properties. The various properties of ultrafine CaCO_3 we synthesized are satisfactory. The synthesis mechanism and application of CaCO_3 with various shapes have been discussed.
