Magnetic suspensions are widely at fabrication of magnetic fluids, which are concentrated resistant dispersing systems. Magnetic suspensions underlie in fabrication of toners for copying engineering, magnetic tapes for record of information. The quality of terminal products largely depends on the dispersion ability of magnetic. It is more reasonable produce highly dispersive magnetic, using a condensation method of synthesizing.It is shown that the degree of dispersion of produced magnetic by a condensation method depends substantially on pH of enviroment. The presence of a excessive acid results in magnification of the dispersion degree and accordingly in a stability improvement of a disperse system. This also allows to obtain a product with pregiven dispersion degree, which is extremely important for improvement of the quality of magnetic fluids. It is shown, that the concentration of suspension on an extent of aggregation of magnetic fragmentsThe conducted investigation allow to plan the dispersity of the terminal product.
