Plate-like magnetic particles

Platelet-shaped multilayered particles wherein the core includes alumina and/or a mixed phase of alumina and silica, the interlayer includes amorphous silica and the sheath includes iron, the iron being present in elemental form and/or in the form of one or more ferriferous compounds selected from t...

More Information
Summary:Platelet-shaped multilayered particles wherein the core includes alumina and/or a mixed phase of alumina and silica, the interlayer includes amorphous silica and the sheath includes iron, the iron being present in elemental form and/or in the form of one or more ferriferous compounds selected from the group consisting of ferdisilicide, maghemite, hematite and magnetite. What is disclosed is a preparative process and the use of the particles in the isolation and separation of organic substances or in enzymatic cleavage reactions and in a magnetically stabilized moving bed.
