Abstract
The present invention relates to a method for fabricating calcium carbonate nanoparticles dispersed in water from ground calcium carbonate of micrometer (μm) order using beads milling. More particularly, the present invention relates to a method for fabricating calcium carbonate nanoparticles dispersed in water by which a complex aqueous slurry comprising coarse ground calcium carbonate having an average particle size of several micrometers (μm) and a surfactant is subjected to beads milling, such that grinding and dispersion in water of the ground calcium carbonate occur simultaneously, and the resultant calcium carbonate nanoparticles have an average particle size of 10-100 nm and a unimodal clustering distribution.
