본문내용
01 Introduction - Al2O3
Fig. 1 Al2O3
•One of the oxide ceramics
• Great physical properties
• Low fracture toughness
• Reduced strength at high Temperature
→ Addition of SiC whisker to alumina compensates for the disadvantages
<중 략>
04 Improvements
* Improvements
1. Use top-down method (milling)
- Reduce the size of Alumina particles
→ Lower sintering temperature
2. Add the SiC powder
- Denser, lower residual stress
