By method of Fe(II) and Fe(III)
salts condensation method magnetite particles have been
obtained. In the interlayer packet of bentonite magnetic composites synthesised. By electron microscopy
shows that the particle size of magnetite and magnetite composite of bentonite is within 0.2-1.0 mµ. The
charges of bentonite particles and magnetite composite of bentonite determied by electrophoresis. It is
shown that the magnetite particles have a positive charge, and the composite of magnetite-bentonite
charged negatively.
Key words: magnetite, magnetic particles, magnetic compositions.
