Results and discussion

Results:
Titanium diboride powder with low particle size has been tested for potential to produce inhalable and respirable dust during handling by DIN 33987-2 and EN 15051-B. Tested TiB2 powder has been shown to contain up to 0,69 mg/kg respirable dust and up to 38.2 mg/kg inhalable dust. According to these results, the powder can be described to be of very low to low dustiness.
