Density

Density is the mass of a material per unit volume. The most common expression of this is g/cm3.

Advanced ceramics vary in density but are typically heavier than plastics but lighter than steel. The density range of the most common materials being between 2 and 6 g/cm3 giving ceramics a weight advantage over most metals .

Hardness

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.

Fracture Toughness

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.

Compressive Strength

Compressive strength is the capacity of a material to withstand loads tending to reduce size. Explained differently, compressive strength resists compression (being pushed together), whereas tensile strength resists tension (being pulled apart).
