The Polar Advantage
Spray-dried/Milled Powders
Polar’s patented process provides agglomerated powder through spray-drying or a de-agglomerated form through various milling process.
Customized Performance
Polar powder can be tailored to meet specific performance requirements for multiple applications. Particle size, surface area, and density can be tightly controlled to improve performance. Powder dopants and additives are available to meet special application performance criteria.
Consistent Purity and Particle Size
Polar provides 3N, 4N, and 5N powders with consistent purity and tight particle size distribution to improve product yields and repeatability
