摘要：

ZrO2-, CeO2-, Y2O3-, La2O3-, and CaO-modified Cr2O3 abrasives were characterized by x-ray diffraction, electron microscopy, and sedimentation analysis. The results indicate the formation of solid solutions in narrow composition ranges. The materials offer a high abrasive ability and ensure residual roughness R-z = 0.04-0.09 mum in polishing precision parts of the ShKh-15 steel, with a product yield of up to 80-82%.
