Abstract. This research was aimed to synthesize calcium carbonate nanoparticles from CaCl2 and Na 2 CO 3 precursors by mechano-chemical route without any subsequent heat treatment of the as-milled powder. The powder mixture was once milled in a planetary ball mill with NaCl as the diluting agent and another time with KCl.
