Single crystal alumina powder

Product Features
Monocrystalline alumina powder is produced through specialized crystal growth control technology, featuring a small specific surface area, clean surfaces, no residual metal impurities or burrs, high sphericity, high α-phase content, low oil absorption value, and a thermal conductivity two-thirds higher than that of ordinary spherical alumina powder. The monocrystalline structure is transparent, significantly reducing viscosity in silicone grease systems. It is currently used in thermal grease and thermal gel systems.
Product Parameters

Product Applications
α-Alumina (α-Al2O3) is widely used in ceramic fillers, bioceramics, armor materials, and transparent high-pressure sodium lamp tubes due to its excellent mechanical, optical, electrical, and biological properties. One of its key applications is as a filler material to enhance polymer performance and expand the application fields of polymers. Compared to ordinary α-Al2O3 particles, spherical single-crystal alumina particles exhibit low viscosity and high fluidity, enabling good dispersion in polymers. Spherical single-crystal alumina powder is currently used in thermal greases and thermal gels.

Packaging and Storage
This product is packaged in inert gas-filled plastic bags and should be stored sealed in a dry, cool environment. It should not be exposed to air to prevent moisture-induced oxidative agglomeration, which may affect dispersion performance and usage effectiveness. The packaging quantity can be provided according to customer requirements, with sub-packaging available.
