【 摘 要 】

The precipitated CaCO3has successfully been synthesized from dolomite. The influence of various temperature and carbonation rate on the morphology, crystal size, phase and structure of the carbonation products were studied. The particles resulted from this process have the crystal size 400-800 nm. The calcite phase wasformed inthe synthesis at 30°C with carbonation rate of 2 and 7 SCFH, and synthesis at 80 °C and 2 SCFH also produces calcite phase. Observations by SEM shows morphology of calcite as so-called schalenohedral.
