Description of key information
The particle size distributions of aluminum trititanium dodecachloride (TiCl3 -AA) were measured twice using Laser Diffraction System. The average values were as follows; D10; 0.78μm, D50;9.35μm, D90; 47.15μm.
And its span is from 4.45 to 5.5.
Additional information
Test dispersions were prepared by dispersing test sample into kerosene.
