Nanometer calcium carbonate(nano-CaCO_3)is a kind of inorganic filler devel-oped by applying recent scientific insights,with high added-value and high return.Itis widely used in many fields such as high-grade pinking ink,coatings and special rub-ber gaskets.At present,China boasts 14nano-CaCO_3 manufacturing technologies,including home-grown intermittentcarbonization,high-gravity method,mul-tistage spray carbonization,non-freez-ing method and membrane dispersion
