Grinding Media The grinding abrasives commonly used in materials preparation are silicon carbide (SiC), aluminum oxide (Al2O3), emery (Al2O3 - Fe3O4), composite ceramics and diamond. Emery paper is rarely used today in materials preparation due to its low cutting efficiency. SiC is more readily available as waterproof paper than aluminum oxide.
