Advantages:
1. High density: over 6 g/cm3, which makes it the densest body of the ceramic products.
2. High hardness: over 9 on Mohs scale, diamond being 10, with a satin-smooth surface finish.
3. High toughness: over 1200 MPa, approx. 4 times in comparison with 95% alumina.
4. Excellent wear resistance, it's much better than aluminum oxide ceramics with longer life cycle.
Application:
Include scissors, knifes, slitters, pump shafts, metal-forming tools, fixtures, tweezers, wire drawing rings,
bearing sleeves and valves.
