Conclusions:
The fraction of calcium nitrate tetrahydrate < 2000 µm, < 100 µm and < 45 µm was determined to be 50%, 2.0% and 1.3%, resp., using the CIPAC MT 59 dry-sieve method.

Description of key information

CIPAC MT 59 dry-sieve test result for calcium nitrate tetrahydrate: 50% is < 2000 µm, 2.0%  is < 100 µm and 1.3% is < 45 µm.
