EC number: 235-120-4
CAS number: 12070-08-5
Mean diameters (distribution type: number) are for the same sample: D90 = 0.89 μm ± 8 % (Urel), D50 = 0.37 μm ± 4 % (Urel), D10 = 0.23 μm ± 14% (Urel).
A guideline study according to ISO 13320:2009 (Particle size analysis - Laser diffraction methods) was conducted for determination of the particle size distribution of the test substance titanium carbide in water as dispersion medium. The following particle size distribution could be determined by laser diffraction analysis: D90 = 4.33 μm ± 8 % (Urel), D50 = 2.07 μm ± 4 % (Urel), D10= 0.70 μm ± 14 % (Urel).
properties of titanium carbide were analysed by the laser diffraction
method according to ISO 13320:2009 (Particle size analysis - Laser
diffraction methods). The particle size distribution was determined
using the particle size analysator MastersizerS from Malvern
Instruments. The following mean diameters (distribution type: volume)
could be determined:
D (v, 0.1) = 0.76 µm D (v, 0.5) = 2.13 µm D (v, 0.9) = 4.34 µm
The following mean volume diameters were determined for titanium carbide:D90 = 4.33 μm ± 8 % (Urel), D50 = 2.07 μm ± 4 % (Urel), D10= 0.70 μm ± 14 % (Urel).
The laser diffraction test using water as dispersion liquid, performed in accordance to ISO 13320:2009 produced the following mean diameters of titanium carbide (distribution type: volume) by applying Fraunhofer approximation:
Thieleke_2021: D90 = 4.33 μm ± 8 % (Urel), D50 = 2.07 μm ± 4 % (Urel), D10= 0.70 μm ± 14 % (Urel).
In the Reach Certificate from 2011 the median values of particle size were in the same range:Certificate Reach_2011: D90 = 4.34 µm, D50 = 2.13 µm, D10 = 0.76 µm
