title = "The precipitation kinetics of nickel powder produced by hydrogen reduction in commercial batch autoclaves",
abstract = "The active particulate processes in the precipitation of nickel powder by hydrogen reduction were investigated on an industrial scale by analyzing the evolution of the particle size distribution (PSD) and its derived moments. Based on this information, an appropriate model based on the moment form of the population balance equation (PBE) was tested. Nickel powder samples were collected from the industrial autoclave after each successive batch reduction (densification) and the PSD analysed using an image analysis technique. The PSD data was then transformed into moments and the experimental values were compared with those simulated using a model based on the moment form of the PBE. The process was characterized by significant aggregation in the first ten densifications followed by a dominance of either aggregation and/or breakage in the later stages of the cycle.",
