摘要

Mono-dispersed NiO precursor particles were prepared by homogeneous precipitation in the presence of urea. Optimal discrimination plan, one of the chemical pattern recognition techniques, was applied to analyze the experimental data and the calculating results were visualized in the mapping figures, in which the different class of samples were divided distinctly and the corresponding semi-experienced mathematic model was deduced. The model can be well used to predict the relationships of the characteristics of the precipitated particles with operational parameters. It proved experimentally that the model fit well with the experimental results and it was quite effective to guide the process design.
