Density
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 .
Materials Ranked by Density
Out of all the grades and materials offered by China Ceramic Parts, Macor offers the lowest density at 2.52 g/cm3 and on the opposite end of the scale our CeramZirc™ grades ranging to a density of 6.05 g/cm3.
Zirconia (ZrO2) - CeramaZirc™
6.05 g/cm3
Unlike traditional ceramics that tend to be hard and brittle, Zirconia offers high strength, wear resistance, and flexibility far beyond those of most other advanced ceramics.

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
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).
