Engineering ceramic materials have attractive properties: high hardness, high thermal resistance, chemical inertness, low thermal conductivity and low fracturetoughness etc.
工程陶瓷材料具有引人注目的特性：高硬度、高耐热性、化学惰性、热传导率低、断裂韧度低等。

It is very difficult to compute fracturetoughness for silicon carbide whisker reinforced ceramic composite theoretically so far.
目前很难对晶须增韧陶瓷复合材料的断裂韧性进行理论计算。

The fracturetoughness of silicon being bigger than ceramic, the cutting efficiency is higher because of the easier brittle chip formation mechanism.
