Manufacturing Process

Calcium carbonate nanoparticles can be synthesized by precipitation from calcium nitrate aqueous solution and saturated sodium carbonate solution. The nanoparticles can be characterized using transmission electron microscopy (TEM), thermogravimetric analysis (TGA), and X-ray diffraction (XRD). The calcium and carbonate ion concentrations help to control the size of the nanoparticles.


The key applications of calcium carbonate nanoparticles are as follows:

  • In drug delivery by loading with hydrophilic protein drugs
  • For potential imaging purposes
  • In coatings, nanowires, plastics, and alloy and catalyst applications.

    What are the magnetic properties of CaCO3?

    • Will Soutter Will Soutter AZoNetwork Team Member says:

      Hi Raja - CaCO3 is diamagnetic, with a molar susceptibility of -3.82 x 10^-5 cm3/mol

  2. Beril Calcite, like most carbonates, will dissolve with Beril Calcite, like most carbonates, will dissolve with India says:

    Can it be blended with polymeric membranes to improve hydrophilicity??
