99 Alumina
High-purity 99 percent alumina ceramics for clean insulation, high-temperature stability, wear resistance and precision ceramic parts.
99 Alumina ceramic components for demanding operating environments.
99 alumina provides higher purity and improved performance compared with standard alumina grades. It is often selected for cleaner environments, higher temperature duty and components where electrical insulation and chemical stability are important.
- Purity requirement and contamination-sensitive contact surfaces
- Operating temperature, atmosphere and cleaning method
- Electrical insulation or vacuum compatibility requirements
- Critical dimensions, surface finish and edge condition
- Whether 99 percent purity is required or a lower grade is sufficient
