Ultrafine particles of CaCO3 were synthesized with micropore dispersion in gas-liquid (slurry) systems.Experiments was conducted on carbonation of Ca(OH)2/H2O system.Micropore plate was used for the dispersion of mixed gas containing CO2.Therefore
the processes of momentum transfer
mass transfer and reaction were enhanced.The results showed that ultrafine particles with diameter about 40nm and specific surface area more than 30m28226;g-1 were prepared successfully.The crystal structure of particles was characterized with BET
