Analytical Characterization of Aluminum, Steel, and

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