Description of key information

As no information is available on particle size distribution of potassium tetrafluoroaluminate, data from its structural analogue multiconstituent aluminium potassium fluoride is used instead. The following data on particle size distribution of multiconstituent aluminium potassium fluoride were obtained using laser diffraction method: D10 = 0.92 μm, D50 = 3.01 μm, D90 = 11.63 μm. 

Additional information

Value obtained in a GLP-compliant and well documented study, adequate for assessment.
