Grinding and Polishing Guide
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.

Aluminium Oxide (Al2O3)
Al2O3 + 2NaOH → 2NaAlO2 + H2O. 2. Reaction with sulphuric acid. Metal oxides are generally basic in nature but aluminium oxide is amphoteric oxide. Hence it acts both as acid and base. In this case, it acts as a base. Al2O3 + H2SO4 → Al2(SO4)3 + H2O. This is a neutralisation reaction. 3. Reaction with hydrochloric acid
