Zirconium Oxide Conductive Ceramic Description
Conductive Zirconium Oxide
(ZrO₂) Ceramics are advanced solid
electrolytes widely used in high-temperature electrochemical applications. By
doping zirconia with stabilizers such as calcium oxide (CaO) or yttrium oxide
(Y₂O₃), oxygen vacancies are introduced into the lattice through charge
compensation mechanisms—enabling excellent oxygen ion conductivity at elevated
temperatures. This makes stabilized zirconia ideal for use in solid oxide fuel
cells (SOFCs), oxygen sensors, and oxygen concentration cells.
Thanks to their ability to
transport oxygen ions, conductive zirconia ceramics are essential in oxygen
detectors for steelmaking, automotive exhaust gas sensors (for air-fuel ratio
control), and hydrogen production systems. Additionally, due to their excellent
electrical and thermal properties, these ceramics serve as high-temperature
electrodes and heating elements, with operational temperatures reaching up to
2100-2200℃in air.
