The comparative preparation of magnetite magnetic liquids by conventional and novel techniques is described and some characteristics of the obtained liquids are discussed. By contrast to conventional technique, according to novel technique the oleic acid was prepared by the interaction of sodium oleate and hydrochloric acid coincidentally with the deposition of the magnetite. It was shown that dispersed...
The preparation of zinc oxide by interphase synthesis is described. The dispersity and phase composition of the obtained sediments are analysed by the methods of scanning electron microscopy and X-ray diffraction. It is concluded that the particles shape and phase of their localization depend on the reaction conditions (temperature, reagent ratio and two-phase system composition).
