Reaction precipitation of amorphous calcium phosphate: Population balance modelling and kinetics

•Reaction precipitation of calcium phosphate is studied in a Y-mixer-tubular reactor.•The process is modelled by using a population balance model.•The set of moment equations is solved by the quadrature method of moments.•The particle size distribution is approximated by a corrected gamma distribution.•The kinetic parameters are estimated by fitting the model to the experimental data.
