Ordered aggregates of ultrafine iron oxide particles: 'Super crystals'
Ultrafine iron oxide particles with a mean diameter of 6.9 nm and a very narrow size distribution have been studied by electron microscopy, Mössbauer spectroscopy, and X-ray diffraction. Electron micrographs and electron diffraction patterns show that the particles form 'super crystals', t...

| Zusammenfassung: | Ultrafine iron oxide particles with a mean diameter of 6.9 nm and a very narrow size distribution have been studied by electron microscopy, Mössbauer spectroscopy, and X-ray diffraction. Electron micrographs and electron diffraction patterns show that the particles form 'super crystals', that is, three-dimensional ordered close-packed structures, with a nearest neighbour distance of 9.1 nm. |
