Hi Dalsenov! We build from the bottom up instead. Often the nanoparticles are produced from metalloorganic precursors or metal salts. By building the nanoparticles from these compunds, you start from atom-level and grow your particles from there. This makes it possible to get extremely narrow size distribution - especially when producing in supercritical conditions (high temperature, high pressure). We do use grinders as well, but to crush agglomerates into finer powders to make them easier to handle and make into dispersions and inks. All the best!
@@FunctionalMaterialsDTI Thanks for your answer! I had in mind pure metals (Cu,Al,Ni,etc).In the meantime I read about "laser ablation".I suppose this is a technology for downsizing as well.Keep up the good work!
Interesting! How do you "grind" a metal to get nanosized particles? Is there a special machine that does that?
