The tremendous enhancement of the physical, chemical, and mechanical properties of materials in their nanocrystalline state is being exploited in a number of frontier technologies; however, concern in the use of nanocrystalline materials is their stability during high‐temperature exposure, either while processing or in service. Reported in this communication is a new solid‐state electrochemical method for the accurate determination of high‐temperature surface thermodynamic properties of nanocrystalline ceramics, using MgAl 2 O 4 as a model compound.
