Aluminum iron oxide nanoparticles have been prepared by heat-treating ammonium hydroxycarbonate complexes with the general formula NH(4)Al(2)Fe(OH)(5)(CO(3)) center dot nH(2)O and have been characterized by X-ray diffraction, IR spectroscopy, differential thermal analysis, scanning electron microscopy, and particle size analysis. The mixed oxide alpha-Al(2-x)Fe(x)O(3) with x = 0.30-0.37 prepared from hydroxy complexes ensures surface roughness values R(a) = 0.005-0.02 mu m in polishing of the ShKh15 quenched steel with an austenite/martensite structure and offers high abrasion rate owing to its enhanced tribochemical activity and the presence of particles in the size range 1-10 nm.
