Particle size distribution is measured by laser instrument (Malvern).Used parameters: presentatiom 5UHD, refractive index powder 3,1255.0,1.
Particle morphology
The SICOMILL production system is based on the principle of fluid-energy milling in order to minimise contamination.A powder produced by this method has a morphology with relative sharp edges and a narrow particle size distribution. |
