03
Processing and use
Processing
- Porosity, grain size, purity, secondary phases and surface finish strongly influence properties.
- Ceramics require flaw-sensitive design and appropriate joining and inspection methods.
Applications
- Wear and seal components
- Electrical or thermal-management parts
- High-temperature fixtures and windows
Selection considerations
- Flexural strength is statistical and geometry dependent.
- Thermal shock depends on conductivity, expansion, strength and component geometry together.

Supply and sustainability
Available in standard compositions and custom processed grades; geometry and finishing can dominate cost and lead time.
Long service life and high-temperature efficiency can offset energy-intensive powder processing and firing.
Strategic context
Supports high-temperature, wear, electrical-insulation and thermal-management systems.
