What Is Alumina powder?
Aluminium oxide is a refined form of aluminium oxide (Al₂O₃), which is obtained by burning and grinding highly pure aluminium oxide. Based on calcining temperature and machining parameters, aluminum oxide powders may be fabricated in a variety of intermediate and alpha phases – each with distinctive surface areas, pores, hardness, and reactive properties adapted to particular industry requirements.
Aluminum oxide, as one of the best chemical stability and mechanical strength in the world, has attracted wide attention in many sectors because of its unique combination of properties: Hard, Low Electric Conductivity, Good Heat Resistance, and Strong Resistance to Acidic and Alkaline Attack. Available in a broad range of grain sizes – from sub-micron to coarse grain – aluminium powder can be accurately defined for every use, regardless of whether it requires a large surface area, a high filling density or a controlled reaction.
Ranging from sophisticated ceramics and electronics to grinding compounds, catalytic carriers, and refractory binders, aluminum oxide has become an essential ingredient for many of the most technologically challenging industries in the world.
Why Choose Alumina Powder?
-
High Purity & Consistent Quality Produced to stringent purity specifications — typically 99% Al₂O₃ and above — alumina powder delivers reliable chemical composition and predictable performance across sensitive applications including electronics, advanced ceramics, and precision manufacturing.
- Precisely Controlled Particle Size DistributionAvailable over a wide range of dimensions, aluminum oxide is available to meet precise technological requirements - from fine sub-micron grades for polishing and thin film use to coarser grades suitable for refractory mixtures and structural ceramic formation.
-
Outstanding Thermal StabilityRetaining structure and chemistry at more than 1600 degrees Celsius, aluminum oxide is essential for high temperature sintering, furnace furniture, heat shield paint, and refractory castable compositions.
-
Excellent Chemical ResistanceResistant for the majority of acids, alkalis, and organic solvents, but also provides reliable performance under the conditions of the chemical attack - prolonging the lifetime of the component and lowering the maintenance requirements of the entire process sector.
-
Versatile Processing CompatibilityAlumina powder integrates seamlessly into diverse manufacturing processes — including dry pressing, slip casting, tape casting, and thermal spraying — giving engineers and formulators the flexibility to optimize both product performance and production efficiency.
業界が直面する課題
Particle Size Consistency
The maintenance of accurate and even grain size distribution in large-scale production lots continues to be a key technological problem that has a direct effect on the properties and quality of the downstream products.
Purity Control
Even a tiny amount of impurities — including silicon, ferric oxide, or sodium — can severely impair the properties of aluminum powder in sensitive applications like electronics, advanced ceramics, and catalytic processes.
Phase Stability at High Temperatures
Controlling the transformation of aluminum oxide (Gamma, Theta, Alpha) during calcining needs to be carefully managed in order to obtain the particular surface area and crystalline structure that is required for every application.
Moisture Sensitivity During Storage & Handling
Aluminum oxide is able to absorb air humidity, changing the chemical composition and fluidity of the surface – so that the correct packing, storage, and processing processes are critical to maintaining the integrity of the product.
Dispersibility in Formulations
Achieving homogeneous dispersion of aluminum oxide in ceramic sheets, refractory mixtures, and paint formulations that do not agglomerate will need to be carefully treated and optimized by the vendor and the end-user.
