The calcium carbonate synthesis process started by mixing between 0.5 M Na 2 CO 3 and 0.5 M Ca(NO 3) 2.4H 2 O solutions. The solution was mixed continuously at a temperature of 27 °C (T = 300 K), with the fixed stirring speed at 800 rpm with different reaction times (5, 10, 15, and 30 min). The solution was filtered to get the precipitated …
