Compressive Strength
Compressive strength is a superior property of advanced ceramics, demonstrating the ability to withstand external forces. This strength is determined by factors such as the material’s structure, the compaction process, and surface finish. By minimizing flaws and ensuring a uniform grain size, ceramic engineers can significantly enhance compressive strength, making these materials ideal for applications demanding high load-bearing capacity.

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.
