Aluminum Oxide (Alumina / Al₂O₃) pellets, also known as alumina pellets, are widely used in various industrial applications due to their excellent thermal, chemical, and mechanical properties. These pellets are composed of high-purity aluminum oxide and are commonly utilized in thin-film deposition, catalyst support, and refractory materials. Alumina pellets are ideal for high-temperature environments, offering exceptional resistance to wear, corrosion, and thermal shock.
Key Applications
- Thin-Film Deposition: Used as a material in physical vapor deposition (PVD) processes, including sputtering and evaporation, for creating high-quality alumina coatings on substrates.
- Catalyst Support: Acts as a durable support material for catalysts in chemical reactions due to its high surface area and inertness.
- Refractories: Used in the manufacturing of refractory linings in furnaces, kilns, and other high-temperature industrial processes.
- Electrical Insulation: High dielectric strength makes alumina pellets suitable for insulating materials in electrical and electronic components.
- Optical Coatings: Utilized in optical thin films for enhancing durability and transmission in UV, visible, and IR ranges.
- Abrasives: Serves as a raw material for high-performance abrasive tools due to its hardness.
