Aluminum oxide (Alumina) is a widely used engineering ceramic known for its hardness, wear resistance, and chemical inertness at high temperatures. High-purity grades offer excellent electrical insulation, corrosion resistance, and hardness. Alumina is commonly used in coating applications, often applied via Atmospheric Plasma Spray. It is used in wear-resistant components like wear pads, seal rings and liners. High-purity alumina also finds applications in electrical, thermal, and biomedical fields, such as insulation and electronic substrates.
