Results and discussion
- Results:
- Hexagonal boron nitride powders with low particle sizes have been tested for their potential to produce inhalable and respirable dust during handling by DIN 33987-2 and EN 15051-B. Tested hBN powders have been shown to contain up to 15.8 mg/kg respirable dust and up to 419 mg/kg inhalable dust. According to these results, the powders can be described to be of low to moderate dustiness.
