Thermally and mechanically treated bones, from non-living animals, and/or eggs, from living animals, transformed into a powdery form, can be used as abrasive materials for jet blasting or to fabricate abrasive papers. This invention describes the use of powders made from incinerated dead animals, said animals coming from land or sea, and/or made from eggs from living animals, said animals coming from land or sea as well. All organic content is eliminated from raw materials through thermal processes. Inorganic end products are crushed and grinded into a powdery form. Powders obtained thereafter, both thermally and mechanically processed, are used as abrasive materials, said materials used as is or mixed with other compounds. These latters can be glued on paper substrates to make abrasive papers, or on abrading wheels, bands or disks, regardless of the underneath material. Abrasive powders can also be used in electrocomposite formulations.
