Strength Hardness | Characteristics of Fine Ceramics

A material's hardness is determined by measuring the size of an indentation made by a sharp diamond pressed strongly onto a material specimen. The hardness of alumina ceramics is nearly three times that of stainless steel; silicon carbide is more than four times harder than stainless steel. This extreme hardness is one of many unique properties that makes Fine Ceramics "super materials" for modern
