Optimised La(2)Mo(2)O(9) materials exhibit superior oxide ion diffusion, exceeding fluorite electrolytes. Enhanced oxygen diffusion in H(2)(18)O/(16)O atmospheres suggests potential for advanced ceramic applications.

Area of Science:

  • Materials Science
  • Solid-State Chemistry
  • Electrochemistry

Background:

  • La(2)Mo(2)O(9) based materials are explored as potential solid electrolytes.
  • Fluorite structured electrolytes are benchmark materials for ionic conductivity.

Purpose of the Study:

  • To investigate oxide ion diffusion in optimised La(2)Mo(2)O(9) materials.
  • To compare ionic conductivity with existing fluorite electrolytes.
  • To understand oxygen diffusion mechanisms under different atmospheric conditions.

Main Methods:

  • Isotope exchange depth profile technique.
  • Secondary Ion Mass Spectrometry (SIMS) analysis.
  • High-temperature conductivity measurements.

Main Results:

  • Optimised La(2)Mo(2)O(9) materials show significantly higher oxide ion diffusion coefficients than fluorite electrolytes.
  • A peak diffusion coefficient of 1.41 x 10(-6) cm(2) s(-1) was recorded for La(1.7)Gd(0.3)Mo(2)O(9) at 800 degrees C.
  • Oxygen isotopic substitution was limited in dry atmospheres but enhanced in H(2)(18)O/(16)O.

Conclusions:

  • Optimised La(2)Mo(2)O(9) materials demonstrate promising ionic conductivity for solid electrolyte applications.
  • The observed diffusion enhancement in humidified atmospheres is consistent with BIMEVOX conductors.
  • These findings highlight the potential of La(2)Mo(2)O(9) based ceramics as advanced oxide ion conductors.
