Aluminum Oxide pellets are high-purity, solid pellets of aluminum oxide commonly used in material science, thin-film deposition processes (like sputtering or evaporation), and as a raw material in ceramics and refractory applications. Known for their high hardness, thermal stability, and chemical resistance, aluminum oxide pellets are crucial in various industrial, electronic, and optical applications.
Composition: Aluminum oxide pellets are composed of Al₂O₃ (alumina) and are typically available in purities exceeding 99.9%, especially for applications that demand minimal contamination. High-purity alumina is essential in electronic and optical applications to maintain quality and performance.
Physical Form: These pellets are small, solid, and often uniform in size, making them easy to handle and load into deposition equipment. The dense, compact form ensures efficient, even melting or vaporization during processing.
High Melting Point: Aluminum oxide has a melting point of around 2072°C (3762°F), making it highly stable at elevated temperatures. This property makes Al₂O₃ pellets suitable for high-temperature applications and thermal coatings.
Thermal Conductivity: While a good insulator of electricity, aluminum oxide has moderate thermal conductivity, which helps in heat dissipation in electronic components.
Chemical Inertness: Al₂O₃ is chemically inert and resistant to most acids and alkalis, which is valuable for applications requiring durability in harsh environments. This resistance ensures longevity in coatings and industrial components exposed to corrosive substances.
Hardness and Wear Resistance: Aluminum oxide is an extremely hard material, ranking high on the Mohs hardness scale (around 9), making it ideal for wear-resistant coatings. This property also makes Al₂O₃ pellets valuable in tools and components that face high abrasion.
Thin-Film Deposition: Used as a target material for creating thin, durable, and insulating films on substrates in electronics, optics, and semiconductor industries.
Ceramics and Refractories: Al₂O₃ pellets serve as raw materials for high-performance ceramics and refractory materials due to their high hardness and temperature resistance.
Optical and Protective Coatings: Aluminum oxide coatings protect surfaces from wear and corrosion, and are also used for anti-reflective and other optical coatings in lenses and display technology.
Catalysts and Catalyst Supports: Due to their high surface area and stability, alumina pellets are used in chemical reactions and as catalyst supports in various industrial processes.
VI HALBLEITERMATERIAL GmbH (VIMATERIAL) employs a stringent quality assurance system to ensure the reliability of our product quality. Strict quality control is implemented throughout the entire production chain, and for defective products, we strictly enforce the principle of rework and redo. Each batch is released only after passing detailed specification tests.
Every batch of our materials is independently tested, and, if necessary, we send samples to certified companies for testing. We provide these documents and analysis certificates with the shipment to certify that our products meet the required standards.
