Abstract
Magnetic iron oxide were synthesized using as the initial materials ferrous chloride (FeCl/sub 2/), ferric chloride (Fe/sub 2/Cl/sub 3/) and ferric Ar gas ambiance. At the same time, the magnetic iron oxide colloid particles were coated by Polysaccharides in a solvent. Polysaccharides magnetite (PSM) complex was synthesized under various conditions. At first, the sample was measured by Dynamic Light Scattering. Next, the influence of the polysaccharide on the saturation magnetization was examined. Third, a sample was observed with the transmission electron microscope. And finally,reduction of the particle diameter was attempted by decreasing polysaccharide molecular weight. It was found that particle diameter and saturation magnetization can be controlled by the methods described.
