Abstract.
The high temperature processing which is needed to anneal out these defects is expensive, possibly incompatible with other materials and processing steps, and causes surface roughening.

Introduction
Ceramic materials have been more and more widely used in various fields due to their superior physical and thermal properties and will become one of the most potential engineering materials.
Experimental procedure and results Experimental materials were supplied by Guangzhou Shichao High Performance Ceramics Company, experimental equipments are American Hysitron high precision nanoindentation measurement system with capacities:vertical resolution is 3nN, lateral resolution is 0.5μN, maximum load is 700mN.
On the other hand, cracks propagate toward to specimen surface and produce lateral cracks, thereby materials are removed.
