Abstract

The industrial scale precipitation of sodium perborate was studied in this work. The courses of solution concentration and crystal size distribution during a batch precipitation run are presented.  From the experimental data, development of the mean crystal size and the standard deviaton of the product size distribution were determined.  The results show a significant increase of the mean crystal size in the early stage of the process.
