Resumen:
Magnetite superparamagnetic nanoparticles (MNP) are becoming one of the firstsnanocommodity products. MNP find a number of applications and they are been produced at relativelylarge scale. The co-precipitation method presents many technical and economical advantages amongalternative processes. However, the relationships between physical and chemical reaction conditionsduring the co-precipitation process and the resulting properties of obtained MNP are not yet fullyunderstood. The novelty of this contribution is the establishment of the cross-dependency effects of themain physical and chemical parameters of the co-precipitation reaction on the properties of resultingMNP. The conditions were varied by following an experimental design. The cristallite size, particle sizeand magnetization of the MNP and the Z-potential and size of their aggregates were selected as mainresponse properties. A set of equations in the form of 4-D surface responses in the space of coprecipitation process variables was obtained and analyzed in terms of the resulting properties. The setof equations is useful to predict, optimize and tailor very precisely the properties of resulting MNP as afunction of reaction conditions
