Ceramic Matrices
Processing
- Cast from slurries or pressed into shape with an organic binder and then fired or sintered at high temps
- Materials are very brittle and sensitive to cracks or flaws.
Applications
- Not used for structural parts
- Whiskers or short fibers can be added to improve strength
- High heat resistance applications: T - 2000F to 4000F
- Nose cones, rocket nozzles, ram-jet chambers.
- Dimensional stability is excellent
- Low dielectric constant that is trasparent to radar, microwaves, etc.
