2 Figure 1. Calcium carbonate scale formation in green liquor pipeline at two kraft mills. CaCO3 has been identified as the main component of the hard scale, particularly at locations downstream of the dissolving tank [14]. A systematic study was conducted at the University of Toronto to examine how CaCO3 forms and what makes the scale hard [5].

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