Lanthanide diffusion in stabilized zirconia was measured. Diffusion coefficients increase with ionic radius, influenced by material type and interactions, not lanthanide type.

Area of Science:

Materials Science
Solid State Chemistry
Ceramics

Background:

Zirconia ceramics are crucial for high-temperature applications.
Understanding lanthanide diffusion in zirconia is key for material design.
Stabilized zirconia (YSZ, CSZ) exhibits unique defect chemistry.

Purpose of the Study:

To quantify lanthanide diffusion in calcia-stabilized zirconia (CSZ) and yttria-stabilized zirconia (YSZ).
To correlate diffusion behavior with ionic radius, activation enthalpy, and defect interactions.
To validate experimental findings with theoretical defect energy calculations.

Main Methods:

Diffusion measurements of stable lanthanides in CSZ and YSZ from 1286 to 1600°C.
Analysis of diffusion coefficients and activation enthalpies.

Correlation of diffusion with ionic radius and interaction parameters.

Main Results:

Lanthanide diffusion coefficients increase with ionic radius in both CSZ and YSZ.
Activation enthalpies were ~6 eV for CSZ and 4-5 eV for YSZ.
An association enthalpy of ~1 eV between cation and oxygen vacancies was found in CSZ, absent in YSZ.
Higher lanthanide diffusion correlated with higher lanthanide oxide-zirconia interaction parameters.

Conclusions:

Lanthanide diffusion in stabilized zirconia is governed by ionic radius and defect interactions.
YSZ exhibits generally faster lanthanide diffusion compared to CSZ due to differing defect associations.
Theoretical calculations support experimental observations, aiding in predicting material behavior.
