Materials and methods
Test guideline
- Qualifier:
- no guideline followed
- Principles of method if other than guideline:
- Particle size distribution was measured by laser diffraction of raised dust in air. The median value is the particle size, which is exceeded by 50% (referring to mass or volume) of the particles. The sample was a white powder. It was dried in a vacuum for 1 h at 50˚C.
- GLP compliance:
- not specified
- Type of method:
- Laser scattering/diffraction
- Type of distribution:
- counted distribution

- Amorphous barium copper zinc borobismuthate
- Molecular formula:
- Not applicable as UVCB
- IUPAC Name:
- Amorphous barium copper zinc borobismuthate
