Micro-Nano Alumina Powder Series (α & γ Phase) | Multi-Scale Materials for Advanced Industries | Aogochem

Redefining Material Performance at Every Scale

In the frontier of advanced materials, performance is dictated by control—control over structure, purity, and most fundamentally, over scale. Aogochem's Micro-Nano Alumina Powder Series provides engineers and scientists with this precise control, offering a comprehensive portfolio of aluminum oxide (Al₂O₃) materials spanning from the micrometer to the nanometer regime, and available in both the alpha (α) and gamma (γ) crystalline phases. This dual-scale, multi-phase approach allows for the exact selection of alumina properties to meet specific application demands: from the superior hardness and thermal stability of alpha-phase powders for wear-resistant ceramics to the exceptional surface area and catalytic activity of gamma-phase nanoparticles. Whether you are sintering a high-strength technical component, formulating a scratch-resistant coating, developing a next-generation catalyst, or achieving a mirror finish in precision polishing, our Micro-Nano Alumina Series delivers the foundational material excellence required. Manufactured to consistent high-purity standards, these powders are engineered to enhance mechanical properties, thermal management, chemical reactivity, and surface characteristics, empowering innovation across industries from electronics and energy to aerospace and chemicals.

Product Series Specifications & Technical Data

Our series is categorized to help you select the optimal grade based on particle size, phase, and target performance. Below is an overview of our core product range. Custom sizes, distributions, and surface modifications are available upon request.

General Physical & Chemical Properties:

• Appearance: White, free-flowing powder.

• Bulk Density: Varies with particle size and morphology (e.g., Nano: ~0.1 g/cm³; Micron: ~0.8 g/cm³).

• Thermal Conductivity (α-phase): High intrinsic thermal conductivity (~30 W/m·K for single crystal), making it an excellent filler for thermal management composites.

• Chemical Stability: Inert to most chemicals, stable in oxidizing and reducing atmospheres at high temperatures.

Driving Innovation Across Key Technology Sectors

The unique properties of micro- and nano-alumina translate into critical performance enhancements across multiple high-growth industries.

• Advanced Ceramics & Composites: Micron-sized alpha alumina is the workhorse for high-alumina ceramics, providing strength and wear resistance for seals, bearings, and cutting tools. Nano alumina acts as a sintering aid, enabling lower processing temperatures and finer grain structures for translucent or high-fracture-toughness ceramics.

• Surface Engineering & Precision Manufacturing: As a premier polishing abrasive, both micron and nano alumina grades are used to achieve ultra-smooth, defect-free surfaces on semiconductor wafers, optical lenses, and hard disk substrates. In coatings, they impart exceptional hardness, abrasion resistance, and corrosion protection.

• Catalysis & Chemical Processes: Nano gamma alumina is prized for its extremely high surface area, serving as an exceptional catalyst support in automotive exhaust systems, petroleum refining (hydrotreating, reforming), and chemical synthesis. Its porous structure maximizes active site availability.

• Electronics & Thermal Management: High-purity alumina powders are used in electronic substrates, package ceramics, and as thermally conductive fillers in adhesives, greases, and encapsulants to dissipate heat from high-power devices like LEDs and ICs.

• Energy Storage: Specialized grades are employed as ceramic coating materials on lithium-ion battery separators, enhancing thermal stability and safety.
