Description of key information

Amount of particles < 100 µm: 0.05% after 32 min. of sieving

Additional information

The particle size distribution of Lanthanum chloride was examined using an orbital shaker with a test sieve with 100 µm mesh size. 10.000 g of test item were shaken for 32 minutes over a tared foil-coated paper. There were no visible particles of the test item on the paper. The weight of the invisible fraction was 5 mg, corresponding to a percentage of 0.05%. So the amount of particles smaller than 100 µm was < 0.1% and therefore no further testing is necessary.

A light microscopic examination confirmed this observation, all particles were greater than 100 µm.
