Effects of Aging Time on The Formation of Calcium Carbonate Polymorphs

In this work, effects of aging time, initial reactant concentration, reactant feeding rate and a polymericadditive on calcium carbonate crystallization were investigated by wet precipitation. The precipitated phasewas aged at specified times. Then the obtained crystal forms were characterized by Fourier Transform InfraredSpectroscopy (FT-IR) and X-Ray Powder Diffraction (XRD) methods. Results showed that the polymorph of thecalcium carbonate crystals was affected by aging time and additive used.
