Precipitation of calcium carbonate by carbon dioxide method

Precipitated calcium carbonate was obtained in laboratory by carbonation of calcium hydroxide suspension: mass concentration of hydrated lime was varied, as well as temperature. The samples of precipitated calcium carbonate were examined for particle fineness, the calcium carbonate content was determined by means of complexometrical titration, and a qualitative phase analysis was carried out by means of the Meigen assay, x-ray diffraction method, and DSC sample analysis.
