Study Notes
Advanced Structural Ceramics
Nuclear Ceramics
- Used in nuclear power generation and radioactive waste disposal
Bio-ceramics
- Used in medical fields for dental and bone implants
Tribological Ceramics
- Resistant to friction and wear
Automotive Ceramics
- Used to make components for automobiles
Problems with Ceramics
- Brittle and difficult to fabricate, form, or sinter
- Can be overcome by using ceramic composites and advanced fabrication, forming, and sintering methods
Magnetic Ceramics
- Made of ferrites (crystalline mineral composed of iron oxide and other metals, M(FexOy))
Optical Ceramics
- Polycrystalline materials produced through controlled crystallization of base glass
- Glass-ceramic materials share properties with both glasses and ceramics
- Properties include:
- High strength
- Toughness
- Translucency or opacity
- Low or negative thermal expansion
- High temperature stability
Issues with Ceramics
- Difficult to machine
- Expensive
- Require special joining methods, as normal welding methods cannot be used
