Abstract: In the recent years, nanosized materials have attracted much attention of many scientists and producers because of tremendous potential and applications in many industries, such as: electronics, optical, chemicals, environment and so on. Precipitated calcium carbonate nanoparticles (PCC) has been widely used as fillers for papermaking, plastics, coatings and agriculture. In this work, we research and develop a novel method (High gravity reactive precipitation – HGRP) to prepare nanomaterials through synthetic experiment of nano-CaCO3 with average size about 70 nm, using gas-liquid-solid reaction system. This paper also describes principles of the method and experimental conditions.
