摘要

X-ray diffraction, IR spectroscopy, particle-size analysis, and chemical analysis are used to elucidate the general mechanisms of the formation of nanoparticulate molybdenum-dioxide-modified Al_(2-x)Fe_xO_3 and Fe_(2-y)Al_yO_3 solid solutions prepared via heat treatment of ammonium hydroxycarbonate cornplexes,(NH_4)_2Al_2Fe(OH)_5(CO_3) ? nH_2O. The addition of molybdenum dioxide (within 0.005 mol %) is shown to enhance the polishing performance of the oxides for final polishing of nonferrous metals and alloys (copper and brass) by a factor of 6-7 relative to unmodified aluminum iron oxides, which is attributable to the increased chemical activity of the abrasive material. The surface roughness value R_a achieved is below 0.005 μm.
