Hello! I am going to perform high energy milling of Cr, Al, and C powders. The material of the grinding media and the container is tungsten carbide. Is there any procedure for cleaning the milling materials after the process to ensure that they are not contaminated with our samples?
Hallo, the question is will you repeat milling processes with the same or similar compositions? In this case the cleaning of your milling jars is not THAT important.
Anyway, probably your first milling process, will have the highest contamination sourcing form your wall materials (W, C, and Co!). It is a question if W and Co is a problem for your produced powders.
Simple cleaning with ethanol and cellulose based tissue, is definitely an easy and valuable option and sufficient when you are using Cr, Al and C repeatability.

Uhm the problem is, the equipment is not ours. They usually use the miller for environmental samples.
Hi Raniella,
If you are looking to speed up your process this might help you alot.
instead of placing beads in wells by hand, they made a device that allows you to dispense beads of all sizes in a plate within 15 seconds.
