Zirconia (Zirconium Oxide) by Daiichi Kigenso Kagaku Kogyo (DKK)
Automobile exhaust catalyst:
Zirconia is used as a catalyst for internal combustion reactions in
automobile engines.
Fine ceramics:
Zirconia is used in technical ceramics for biomedical implant, automotive
and armor applications.
PZT:
Zirconia is used in the production of piezoelectric multi-layer ceramic capacitors and
resonators for electronic circuitry.
Dental:
Zirconia is used to produce subframes for dental restorations, and is valued
for its translucency.
Oxygen sensors:
Zirconia is used to make oxygen sensors for use in atmosphere control
applications for materials processing, as well as air-to-fuel ratio control in
combustion reactions in automobile engines.
Electronics:
Zirconia is used as a resistive heating element and as an electrolyte in solid oxide fuel cells.
