Summary
Serial sectioning and charge contrast imaging reveal the 3-D microstructure of gibbsite particles. This technique visualizes volumetric relationships and confirms image detail relates to crystallization processes.
Area of Science:
- Materials Science
- Crystallography
- Microscopy
Background:
- Gibbsite microstructure influences its properties and formation.
- Understanding gibbsite crystallization requires detailed microstructural analysis.
Purpose of the Study:
- To visualize the three-dimensional (3-D) microstructure of gibbsite particles.
- To correlate charge contrast image features with gibbsite microstructure and crystallization.
Main Methods:
- Iterative serial sectioning of gibbsite particles in epoxy resin.
- Charge contrast imaging of 2-D sections.
- Three-dimensional (3-D) reconstruction of microstructural features.
Main Results:
- Successful 3-D reconstruction of gibbsite microstructures from serial sections.
- Confirmation that charge contrast image detail reflects microstructure.
- Observed microstructural features linked to gibbsite crystallization processes.
Conclusions:
- The applied method effectively visualizes 3-D relationships in gibbsite microstructure.
- Charge contrast imaging provides insights into crystallisation mechanisms.
- Further investigation into the nature of observed microstructures is warranted.
