Abstract
Ultrafine powders of the binary (Cr2O3, Fe2O3, SnO2)-Al2O, systems wer e synthesized by introducing aqueous solutions containing metal salts into a high temperature inductively coupled plasma, and the distributi on of component oxides was investigated by transmission electron micro scopy and electrophoretic mobility measurements. For the Cr2O3-Al2O3 s ystem, each component independently constituted its particles that wer e homogeneously distributed in the powder. With the Fe2O3Al2O3, the tw o components formed solid solutions. In the SnO2-Al2O3, each component comprised the powders where SnO2 had a strong tendency to occupy the particle surface.
