Flash sintering is a new technique that applies an electric field at a material characteristic temperature to pass current through a ceramic in order to enhance the diffusion for sintering. The mechanism for flash sintering is highly contentious so the effect of electric field on crystal structure is studied to help elucidate this mechanism. The change in d-spacing of different planes can explain this effect. The behavior of ZnO is studied under flash conditions, both in situ through use of energy dispersive x-ray diffraction (EDXRD) and in the lab through use of scanning electron microscopy (SEM). Peak behavior during flash sintering is used to determine specimen temperature and geometry of the lattice expansion.
