99.99% Alumina Powder
This listing offers 99.99% purity alumina powder, a 4N grade aluminum oxide (Al2O3) with nano-sized alpha-phase particles. The primary particle average size is 40 nm, and the D50 particle distribution can be tailored between 1-40 µm based on client requirements. The material exists in three phase states: α, θ, and γ, making it suitable for precision applications where particle uniformity and purity are critical.
The powder is a premium industrial abrasive and ceramic raw material, widely used in the production of cutting tools, wear-resistant coatings, and LED substrates. Its high purity and controlled particle size distribution make it ideal for advanced ceramics and refractory applications. Standard industry use includes synthetic stone, phosphor production such as tricolor, long afterglow, and YAG phosphor, as well as luminous powder manufacturing.
Buyers typically source this alumina powder for high-temperature structural components, precision polishing, and specialized ceramic formulations. The product is exported in sealed drums or double-layer bags to prevent moisture absorption during transit. Importers should confirm packaging specifications and handling requirements to ensure product integrity upon delivery.

Sourcing 99.99% Alumina Powder from Guangzhou Kingsky Material Company Ltd. - China Import Guide
Before ordering, verify the phase state of the alumina powder, as the α, θ, and γ phases have distinct properties that may impact your application. Confirm the D50 particle size distribution and primary particle size to ensure they align with your processing requirements. It is also advisable to request a certificate of analysis (COA) to validate the 99.99% purity claim.
Discuss logistics details such as Incoterms, which typically include FOB or CIF for bulk material shipments from China. Lead times can vary, so confirm the supplier’s production schedule and transit time, especially if your project has tight deadlines. Payment terms should also be clarified, as they may vary based on order volume and your relationship with the supplier.
Inspection and quality checks are critical for high-purity materials like this alumina powder. Request samples for independent testing to verify purity, particle size distribution, and phase composition. Ensure the packaging meets your standards for moisture protection, and confirm that all documentation, including material safety data sheets (MSDS) and COA, is provided with the shipment.
