MNP find a number of applications and theyare been produced at relatively large scale. The co-precipitationmethod presents many technical and economical advantages amongalternative processes. However, the relationships between physicaland chemical reaction conditions during the co-precipitation processand the resulting properties of obtained MNP are not yet fullyunderstood. The novelty of this contribution is the establishment ofthe cross-dependency effects of the main physical and chemicalparameters of the co-precipitation reaction on the properties ofresulting MNP. The conditions were varied by following anexperimental design. The cristallite size, particle size andmagnetization of the MNP and the Z-potential and size of theiraggregates were selected as main response properties. A set ofequations in the form of 4-D surface responsesinthe space of co-precipitation process variables was obtained andanalyzedin terms of the resulting properties. The set of equations is usefulto predict, optimize and tailor very precisely the properties ofresulting MNP as a function of reaction conditions.
