Y2O3–Al2O3 microsphere crystallization analyzed by electron backscatter diffraction (EBSD)

Electron Backscatter Diffraction (EBSD) Technique and Materials Characterization Examples

The term “electron backscatter diffraction” (EBSD) is now synonymous with both the scanning electron microscope (SEM) technique and the accessory system that can be attached to an SEM. EBSD provides quantitative microstructural information about the crystallographic nature of metals, minerals, semiconductors, and ceramics—in fact most inorganic crystalline materials. It reveals grain size, grai...

Possibilities and Limits of Phase Identification by Electron Backscatter Diffraction (EBSD) in the SEM

Electron Backscatter Diffraction (ebsd) – the Method and Its Applications in Materials Science and Engineering

The present work gives a brief overview of the current status of the electron backscatter diffraction (EBSD) technique. The fundamentals of the production of Kikuchi patterns are first discussed. An experimental set-up for the automated obtaining and processing EBSD patterns in scanning electron microscopy (SEM) is subsequently described and the relevant calibration and automatic Kikuchi patter...

Textural analysis of a microcrystalline quartz using X-Ray and Electron Backscatter Diffraction (EBSD) techniques

An unusual microcrystalline quartz texture has been recognized in the investigation of pervasively silicified ore-bearing horizons occurring in the uppermost part of carbonate platform sequences of different ages (from Precambrian to Mesozoic) and of different geotectonic settings. This peculiar texture has been labeled “grid-work texture”, and derives only by a rather fast and preferred crysta...

Distinguishing Biologically Controlled Calcareous Biomineralization in Fossil Organisms Using Electron Backscatter Diffraction (EBSD)

Although carbonate-precipitating cyanobacteria are ubiquitous in aquatic ecosystems today, the criteria used to identify them in the geological record are subjective and rarely testable. Differences in the mode of biomineralization between cyanobacteria and eukaryotes, i.e., biologically induced calcification (BIM) vs. biologically controlled calcification (BCM), result in different crystallogr...
