YSZ has a number of applications:
- For its hardness and chemical inertness.
- As a refractory (in jet engines).
- As a thermos barrier coating in gas turbines.
- As an electro-ceramic due to its ion-conducting.
- Used in the production of a solid oxide fuel cell (SOFC). YSZ is used as the solid electrolyte.
- For its hardness and optical properties in monocrystal form.
- As a material for non-metallic knife blades.
- In water-based pastes for do-it-yourself ceramics and cements.
- YSZ doped with rare-earth materials can act as a thermographic phosphor and a luminescent material.
- As a high precision alignment sleeve for optical fiber connector ferrules.
