Fracture Toughness
The ability to resist fracture is a mechanical property of materials known as fracture toughness. For advanced ceramics it uses a critical stress intensity factor known as KIC where the fracture normally occurs at the crack terminations.
Density
Density is the mass of a material per unit volume. The unit of measurement can be expressed in different ways and is referred us as g/cm3 but another measurement value is kg/m3.
Hardness
One of the most valuable characteristics of advanced ceramics in high-performance applications is their extreme hardness. Hard ceramic materials are used for a wide range of applications in diverse fields and applications such as cutting tools for milling and grinding.
