Trusted Purity and Surgical Precision That Protects Health

Polar supplies 4N and 5N alumina with low impurities, narrow PSDs, and consistent morphology—ideal for biocompatible, high-strength medical ceramics. Whether you're pressing, sintering, or machining, our ultra-high-purity alumina supports the performance, safety, and reliability modern healthcare demands.

The Challenge:
Purity, Strength, and Safety Must All Align

Producing ultra-high-purity alumina for medical ceramics is uniquely demanding. Materials must be ultra-pure to avoid trace contaminants like Fe or Na that can cause inflammatory reactions or device failure. At the same time, they must offer high strength and wear resistance, with tight control of particle size and morphology to ensure dense, defect-free ceramics. Add the need for regulatory compliance—with full traceability and qualification to standards like ISO 13485—and it becomes clear: medical-grade ultra-high-purity alumina requires precision across purity, performance, and documentation

How We Help:
