Flexural Strength

Flexural strength, also known as bending strength, modulus of rupture or transverse rupture strength, is defined as the maximum stress in a material just before it yields in a bending test

Advanced Ceramics with low flexibility, compared to other materials like metals, normally have lower flexural strength and tend to cataclysmically fail on reaching their maximum test yield instead of deforming.

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.

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).

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.
