Leading the market in purity and structural consistency
In the hierarchy of advanced technical ceramics, Nano Alumina Powder (Al₂O₃) stands as the bedrock of innovation. As a premier China Nano Alumina Powder Manufacturer, Shanghai Creative Advanced Materials Co., Ltd. (SCA) has spent over 19 years refining the synthesis of alpha and gamma-phase powders. Unlike traditional alumina, nano-scale particles (typically <100nm) offer a colossal surface-area-to-volume ratio, fundamentally altering the thermodynamic and mechanical properties of the end products.
Our manufacturing philosophy adheres to the strict Search Quality Rater Guidelines by prioritizing Experience, Expertise, Authoritativeness, and Trustworthiness (E-E-A-T). We don't just supply powder; we provide an "Information Gain" through comprehensive material characterization data, ensuring that our clients in the semiconductor, aerospace, and energy sectors achieve predictable results in high-stress environments.
Established in the Shanghai Industrial Comprehensive Development Zone, we integrate R&D with precision mass production.
Bridging the gap between lab-scale precision and industrial-scale efficiency
Focusing on the 4N (99.99%) and 5N (99.999%) purity thresholds using modified Bayer processes and hydrothermal synthesis to eliminate trace metallic impurities (Fe, Na, Si) that compromise dielectric strength.
Developing silane-coupling and polymer-grafting techniques for nano alumina to prevent agglomeration in resin matrices, essential for the next generation of EV battery thermal interface materials (TIMs).
Utilizing machine learning to optimize the calcination temperature profiles, achieving a perfect spherical morphology for high-load ceramic injection molding (CIM).
How China's Nano Alumina is transforming global industries
Coating polyolefin separators with our Nano Alumina increases thermal stability and prevents dendrite-induced short circuits, extending the life of lithium-ion batteries in harsh climates.
Our 50nm Alpha-Alumina provides the necessary hardness and uniformity for Chemical Mechanical Planarization, ensuring atomic-level flatness on silicon wafers.
By sintering our nano-powders at high pressure, we produce ceramic plates with unparalleled fracture toughness for helicopter and personnel protection.
Utilized in plasma-sprayed coatings for turbine blades, our alumina provides a robust barrier against oxidation and extreme thermal gradients.
Biocompatible high-density alumina produced from our powders offers the wear resistance required for hip replacements and dental implants.

Insight from our Technical Support Team
Alpha Alumina (α-Al₂O₃) is thermodynamically stable and has a high hardness (9 on Mohs scale), making it ideal for abrasives and ceramics. Gamma Alumina (γ-Al₂O₃) has a high surface area and porous structure, making it superior for catalyst supports and coatings.
We use ICP-MS (Inductively Coupled Plasma Mass Spectrometry) to detect trace elements at the parts-per-billion level. Our purification process removes heavy metals and alkali metals to ensure zero contamination in semiconductor applications.
Yes, we offer custom silane-treated or stearic acid-treated powders to ensure compatibility with epoxy, polyurethane, or other polymer systems for thermal management solutions.
Standard catalog items ship within 7 days. Custom-engineered powders or high-volume industrial orders typically have a lead time of 14-21 days, depending on the modification requirements.
