Product Description

Product Description

Alumina / Aluminum oxide powder  

Product Overview:

‌High-Purity Calcined Alumina Powder for Industrial Applications‌

Our calcined alumina powder is a premium-grade ceramic material, meticulously processed through high-temperature calcination to achieve exceptional purity, hardness, and thermal stability. With a particle size distribution tailored for precision applications, it delivers superior performance in demanding industrial environments.

Key Features:

‌Controlled Surface Area‌: Optimized BET surface area (e.g., 5–15 m²/g) enhances catalytic activity and adsorption capacity, critical for chemical processing and environmental applications.

‌Low Thermal Expansion‌: Minimal thermal expansion coefficient ensures dimensional stability under extreme temperature cycling, reducing failure risks in high-performance ceramics and aerospace components.

‌High Purity‌: ≥99.5% AL2O3 content for critical industries.

‌Controlled Particle Size‌: Customizable D50 (1–10μm) for flowability and sintering efficiency.

‌Superior Hardness‌: Mohs hardness of 9 for wear resistance.

‌Thermal Stability‌: Endures up to 2000°C for refractory applications.

‌Chemical Inertness‌: Resistant to acids, alkalis, and solvents.

‌Controlled Surface Area‌: Optimized BET for catalytic/adsorption uses.

‌Low Thermal Expansion‌: Ensures dimensional stability in harsh environments.

Applications:

‌Semiconductor Industry‌: Used as a substrate material for integrated circuits (ICs) due to its excellent electrical insulation and thermal conductivity, ensuring reliable performance in microelectronics.
‌Medical Implants‌: Certified for biocompatibility, alumina powder is utilized in orthopedic implants (e.g., hip replacements) and dental prosthetics for its wear resistance and non-toxic properties.
‌Energy Storage‌: Acts as a separator or coating material in lithium-ion batteries, improving safety and thermal stability during charge/discharge cycles.
‌Environmental Filtration‌: Employed in water purification systems and air filters for its high surface area and adsorption capacity, effectively removing heavy metals and pollutants.
‌Advanced Coatings‌: Applied as a protective layer on aerospace components, automotive parts, and cutting tools to enhance corrosion resistance and durability under extreme conditions.
‌LED Lighting‌: Serves as a phosphor host material in solid-state lighting (SSL), ensuring efficient light emission and long-term stability in high-brightness LEDs.
‌Nuclear Engineering‌: Used in radiation shielding and control rods due to its neutron absorption capabilities and high-temperature resistance in nuclear reactors.
