The Various Concentration Effected on Crystallite Size of Calcium Carbonate
The calcium carbonate was extracted from Pomacea Canaliculata Lamarck (Cherry shell) by using the hydrothermal method. Cherry shell was washed and crushed by DI water and mortar. The powder size was analyzed by particle (aperture Size 63 μm), added x HCl (x = 2, 3, 4) and y Na2CO3 (y = 1, 1.5, 2) mixed with fine powder from Cherry shell. The mixed power was filtered annealed by autoclave at controlled temperature at 333 K for 20 h. The crystal structure was characterized by X−ray diffraction method. The phase transformation of CaCO3 was analyzed by Fourier transform infrared spectroscopy (FTIR). The morphology of Cherry shell and CaCO3 powders were observed by using scanning electron microscope (SEM). It was found that the extracted CaCO3 shows single phase of CaCO3 crystal structure. Smallest crystallite size was found about of 0.54 μm.
