NANOSTRUCTURED COMPOSITE METAL OXIDE MATERIAL, PRODUCTION METHOD AND USE

摘要

The present invention relates to a nanostructured zirconia alumina compound material which is characterized in that the content of different elements of Al, Zr, Hf, Y, Ce and O is less than 100 ppm, the Cl content is less than 1 ppm, at least one of the components has a mean grain size in the final material of less than 500 nm, and at least 1/10 of the particles is in an intragranular position. A further subject matter of the invention is the method for producing said material and also the use thereof.
