High Purity Alumina Powder
High purity alumina powders are known for their high melting point, hardness, chemical inertness, electrical insulation, and thermal conductivity. High purity alumina powders are essential in a wide range of high-tech applications including:
- Sapphire and ruby crystal growth
- LED substrates and phosphors
- Advanced ceramics and ceramic substrates
- Lithium battery separator coatings
- Thermal interface materials
- Semiconductors and electronic components
- Polishing and abrasives for precision optics and metals
At AdValue Technology, we offer a wide range of alumina powders for diverse applications. Both alpha and gamma alumina powders are available. Particle size can range from sub-micron particles to 500 microns. The purity level of our alumina powders range from 99.9%, 99.99%, 99.995% to 99.999%.
