Materials and methods
Test guideline
- Qualifier:
- no guideline followed
- GLP compliance:
- no
- Type of method:
- x-ray diffraction (XRD)
- Details on methods and data evaluation:
- A suitable amount of particles (~0.5g) was packed in a plastic sample holder and a glass slide used to flatten the surface. The crystallite phase was determined using a Bruker ASX-D8 X-Ray Diffractometer (XRD) using Cu K(alpha) radiation. The operation current and voltage was 40mA and 40kV respectively. The scan ranged from 5o to 85o with a step size of 0.02o and a scan speed of 0.40 second/step. The aperture slit size directing the x-ray source was 0.2mm.

Results and discussion
Applicant's summary and conclusion
- Conclusions:
- XRD patterns for NM110, NM111, NM112 and NM113, indicating that the only detected phase was hexagonal wurtzite zincite
- Executive summary:
CSIRO, 2012 investigated the crystallite phase of the nanomaterials. The crystalline phase was determined using a Bruker ASX-D8 XRD using Cu K(alpha) radiation. The operation current and voltage was 40 mA and 40 kV respectively. The scan ranged from 5° to 85° with a step size of 0.02° and a scan speed of 0.40 second/step. The aperture slit size directing the x-ray source was 0.2 mm. XRD patterns of the four ZnO samples are shown in the attached Figure and indicated that all ZnO nanomaterial samples were in a hexagonal wurtzite zincite crystalline phase.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
