What is Flexural Strength?
Flexural strength, also known as bending strength, modulus of rupture, or transverse rupture strength, is the maximum stress that a material can withstand before failing in a bending test.Advanced ceramics exhibit a range of flexural strengths depending on the ceramic material tested. The range is broad and materials based on Zirconia, ATZ or Silicon Nitride compositions exhibit relatively high bending strengths. Unlike metals, which deform before breaking, ceramics are purely elastic in nature and will fracture upon reaching their maximum yield.
Materials Ranked by Flexural Strength
CeramAlox™ Ultra Pure’s compressive strength performance characteristics are the highest compared to all other materials. This is closely followed by Zirconia Toughened Alumina, Silicon Carbide, and Silicon Nitride and others.
Alumina-Zirconia (ATZ)
Flexural Strength: 1800 MPa
Key Features: High hardness, superior wear and corrosion resistance, and excellent fracture toughness. Best For: High-stress applications requiring durability and reliability.
Zirconia (ZrO2)
Flexural Strength: 1000 MPa
Key Features: Advanced ceramic composite, reinforced with alumina platelets for enhanced toughness. Best For: Applications needing superior fracture toughness and resilience.
Silicon Nitride (Si3N4)
Flexural Strength: 970 MPa
Key Features: Versatile mechanical, thermal, and electrical properties. Best For: High-temperature and high-load applications.
Zirconia-Alumina (ZTA)
Flexural Strength: 850 MPa
Key Features: Combination of high hardness, strength, wear, and corrosion resistance. Best For: Industrial applications where toughness and durability are crucial.

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 loadstending to reduce size. Explained differently, compressive strength resistscompression (being pushed together), whereas tensile strength resiststension (being pulled apart).
Fracture Toughness
The ability to resist fracture is a mechanical property of materials knownas fracture toughness. For advanced ceramics it uses a critical stressintensity factor known as KlC where the fracture normally occurs at thecrack terminations.
