Abstract
The present invention provides a process for preparing a precipitated calcium carbonate product. The process comprises the steps of preparing slaking quick time to obtain slaked lime; and subjecting the slaked lime, without agitation, without prior cooling in a heat exchanger, and in the absence of any additives, to carbonation with carbon dioxide as to produce PCC. The newly prepared product develops better performance thanks to improved resistance during processing.
