Thx for your replies so far.
Just to give a little more info:
I need the particles for calibrating laser diffraction sensors. Black particles are necessary due to the theory of laser diffraction which postulates complete absorption in the ideal case. Besides being spherical, the material has to...
Hi,
I am currently searching for a possibilty to get spherical glassy/vitreous carbon particles. I need them as a reference material for particle size analysers since glassy carbon offers a set of amazing properties. The desired particle size is between 100 and 1000 microns.
For initial test...
