5n purity alumina from a patented process
Our innovative manufacturing process focuses on improving yield and reducing total cost of ownership for our customers. We combine hydrometallurgy and pyrometallurgy to produce top quality HPA cost effectively at lower temperatures, utilizing less power, fewer process steps and improving the consistency of our product’s purity and form factors.
Consistent chemistry and reduction of key impurities
Improved customer product yields with higher throughput
Significant customer cost reduction vs competition
3N to 5N Alpha Alumina Powders
Polar HPA powders have consistent purity, tight particle size distribution, can be customized to improve product performance, and are tailored to improve product yields and repeatability.
5N High Density Pellets
Polar higher-density pellets maximize packing density and reduce micro-bubbles to increase furnace throughput and improves sapphire crystal growth yields.
Sapphire Crystal Growth
For LEDs, Optics, Semiconductors and Protective Glass
For Semiconductor Equipment and Chip Packaging, Cutting Tools and Matrix Composites for Aerospace, Green Energy and Industrial Uses
For Lithium-Ion Battery Separators and Anode Materials for Electric Vehicles and Energy Storage Systems
The Polar Advantage
Our environmentally sustainable process utilizes less power, has fewer steps, and recycles nearly all process materials lowering our carbon footprint and our customers’ carbon footprint.
Consistent delivery of products is tailored to meet our customer’s performance, quality, and total cost of ownership needs.
