In situ investigation of the surface morphology evolution of the bulk ceramic Y2Mo3O12 during crystal water release

Abstract

The surface morphology evolution of the bulk ceramic Y₂Mo₃O₁₂ during the release of crystal water is followed in situ for the first time using atomic force microscopy. It is found that both the shape and size of individual grains and the integration morphology of the sample exhibit dynamic changes with increasing temperature. We believe that the surface morphology evolution of the sample with increasing temperature is closely correlated with the forces induced by the contraction and expansion of the lattice during crystal water release in two different stages.
