Abstract: Processes of dry surface modification(with titanic acid ester,aluminic acid ester,boric acid ester,and phosphoric acid ester etc.as coupling agents) and aqueous surface modification(with stearic acid/salt,phosphate,sulfonate,condensed phosphoric acid,and quaternary ammonium salt etc. as surfactants) of nanometer calcium carbonate(NPCC) as well as characteristics of those surfactants were reviewed.Various new surface modification technologies,including stuffings,composite coupling agent,reactive monomer,active macromolecules,polymers,plasmas,and super dispersants etc.,were introduced as well. Finally,the future research direction of NPCC were discussed.  

Key words: nanometer calcium carbonate, dry modification, aqueous modification, coupling agent, surfactant
