Fine Ceramics, sometimes referred to as "advanced ceramics," are engineered materials that support the development of cutting-edge technology.

Rigidity—Less Elastic Deformation Compared to Metals

Fine Ceramics (also known as "advanced ceramics") possess high rigidity, which is measured by inspecting the elasticity of a specimen after applying a load. Materials that display less elastic deformation under load possess higher levels of rigidity. The coefficient of extension with respect to a load is called Young's modulus.
Using Young's modulus to measure rigidity, alumina and silicon carbide display nearly double the values of stainless steel. Why is high rigidity advantageous? It allows ceramic components to be manufactured to much higher levels of precision with regard to size and shape. In some cases, large mechanical stresses are generated on a material while it is being ground to final specifications. The less deformation that occurs during this process, the more precisely the parts can be processed.

Rigidity, also known as "stiffness," is generally measured using Young's modulus. It can be defined as the "force necessary to bend a material to a given degree."
As shown in the graph below, Fine Ceramics are highly rigid materials, according to Young's modulus. This makes their machining accuracy high enough to enable them to be used for high-precision parts.
