Abstract

CaCO3 nanoparticles were synthesized from CaCl2 and Na2CO3 using a new, fast and straightforward technique. Factors affecting on the particle size such as the concentration of Ca2+ and CO32-, PEG weight dissolved in Ca2+ solution, flow rate, temperature, media type, PEG weight dissolved in the used medium, the concentration of CO32-, stirring speed, medium volume and additive dissolved within Ca2+ solution were investigated. The obtained particles were characterized by SEM, XRD, EDS, IR and TGA. The characterization clarified that the particles prepared were spherical with a size range of 19-30 nm, ultra-pure, and calcite. Moreover, the preparation system was redesigned to be a continuous preparation system. The histogram showed that the CaCO3 nanoparticles obtained were homogenous in size (30 nm). Finally, the obtained nanoparticles were utilized in the preparation of nanoporous PVC film with pores size range 80-120nm
