| Abstract: | Calcium carbonate ultrafine particles with six different shapes (including chain, plate, cube, spindle, sphere and needle) were synthesized. The carbonation rate affected the crystal nucleation and growth of calcium carbonate. The change of viscosity in carbonation of lime suspension was studied. Chain-like calcium carbonate products with different grain size were synthesized. |
