99.5% Alumina (Al2O3)
99.5% Alumina (Al2O3) is one of the most widely specified, general-purpose technical ceramics. It is very hard and wear resistant, with high compressive strength, making it suitable for high-intensity environments. It's best suited for applications where smaller grain size is not required.
Attributes
- Crystal Structure: Hexagonal
- Thermal Shock Resistence: 200
- Electronic and semiconductor applications
