Electron channelling contrast imaging (ECCI) applied to a fresnoite dendrite grown via electrochemically induced nucleation
Source abstract
Abstract
Abstract Electrochemically induced nucleation (EiN) may be used to locally trigger the growth of Ba-fresnoite (Ba2TiSi2O8) in a glass melt leading to the growth of macroscopic dendrites. Applying a Czochralski-like procedure enables to grow such dendrites into macroscopic, glass-permeated single crystals, making them a viable alternative to true single crystals e.g. for piezoelectric applications. Here the defect structure of a dendrite resulting from EiN is analyzed using scanning electron microscopy (SEM), electron backscatter diffraction (EBSD) and electron channelling contrast imaging (ECCI). No indications of crystal defects during growth are observed, illustrating a high degree of perfection in the crystal lattice resulting from dendritic growth after EiN.
