Calcium Carbonate (CaCO3) Nanoparticles, nanodots or nanopowder are spherical high surface area particles. Nanoscale Calcium Carbonate Particles are typically 10 - 80 nanometers (nm) with specific surface area (SSA) in the 30 – 60 m 2 /g range. Nano Calcium Carbonate Particles are also available in passivated and Ultra high purity and high purity and coated and dispersed forms. Research into applications for Calcium carbonate nanocrystals has focused on use in drug delivery by loading them with hydrophilic protein drugs and for their potential imaging, biomedical and bioscience properties and for use in coatings, plastics, nanowire, and in alloy and catalyst applications.
