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.

These carbides are very refractory (melt over 2350 C) and they, with oxycarbides, retard the reduction process [24]. Depending on the silicon concentration, equilibrium carbide may appear in different composition: Al4C3 and Al2OC (at low silicon), Al8SiC7 (at higher silicon), SiC (more than 30% Si).
