PRECIPITATED CALCIUM CARBONATE (PCC) WITH DEFINED GRAIN SIZE AND GRAIN SIZE DISTRIBUTION AND METHOD FOR THE PRODUCTION THEREOF

摘要

The invention relates to a process for the preparation of precipitated calcium carbonate (PCC) with a defined particle size and defined grain size distribution. Furthermore, the invention PCC, which is prepared by the process and having a defined particle size and defined grain size distribution is concerned. The invention is among other things based on the finding that the specific molar energy input of the decisive parameters for controlling the grain size.
