X-ray diffraction, IR spectroscopy, and chemical analysis are used to elucidate the general mechanisms underlying the formation of nanoparticulate solid solutions based on Al2– хFeхO3 and Fe2 –yAlyO3 modified with molybdenum dioxide, zirconium dioxide, and yttrium oxide and prepared by heat-treating ammonium hydroxocarbonate complexes, such as NH4Al2Fe(OH)5(CO3)2. The addition of modifying oxides (within 0.005 mol %) is shown to enhance the polishing ability of the solid solutions for finish polishing of nonferrous metals and alloys (copper and brass) by a factor of 5–7 relative to unmodified aluminum iron oxides, which is attributable to the increased chemical activity of the abrasive material. A modified aluminum iron oxide containing 0.001–0.003 Y2O3 is more effective in polishing titanium. The surface roughness thus achieved is Ra = 0.005–0.006 μm.
