Figure 6
Transmission electron micrographs and selected-area electron diffraction patterns from aggregates of brucite grains. The samples were heated at (a), (b) 383 K or (c), (d) 523 K. Each sample consists of brucite grains smaller than 200 nm in size. Diffraction rings indicated with filled triangles are from brucite. The 523 K sample also shows very weak diffraction rings from periclase, MgO (indicated with open triangles). The periclase grains are artefacts resulting from dehydration of the brucite due to electron-beam damage during TEM observation.
