The FSEM images of the calcium carbonate aged for different times are shown in (Fig 10. It can be seen that the calcium carbonate was still in the growth state with irregular morphologies when the aging time was 0 h (image 10a) and 0.5 h(image 10c). When the aging time is 1 h, spherical like calcium carbonate with regular morphology was obtained. With the increase of the aging time to 6 h, the spherical like vaterite became to dissolve and show irregular surface. Further increase the aging time would result in the crystallization of the dissolved vaterite to cubic calcite. When the aging time reached to 12 h, the morphology of the calcium carbonate tended to be stabilized, and the content of the vaterite could be as high as 86.2%. In summary, with the increase of the aging time, the content of the vaterite in the sample decreases, and part of the vaterite became to dissolve and transfer to calcite.
