Milling down copper oxide
For some experimentation I'd like to have some super fine CuO.
As an anti cake or catalyst for AN, or for Nanothermites for example.
Any stuff I could find is 63µm/200mesh or larger.
I'd like to have something like 5µm.
Do you have any idea if does make any sense to mill this down myself? I could use ceramic or steel balls in my ballmill for extra hard impacts.

You could try making it yourself by decomposition of Cu(OH)2. That will give an extremely fine powder.

5µm is much finer than your typical ball mill would achive in any reasonable lenth of time or perhaps in any length of time.
I suspect the decomposition method Cheddite Cheese mentioned wouldn't produce such a fine powder, it's definately worth a try but you'd need a
microscope and a reference material to confirm the particle size.

I was under the impression that such oxides are rather brittle and thus mill fine, in contrast to ductile metals.
But I've never tried it thus far.

Yes!
That ranks pretty high on my buy list for the future, but I'd want a proper one and I'm pretty down and out...
Since a stage micrometer would be another expensive thing - What would you guys use as a reference material?
Something that has a rather narrow size distribution, but what?

So just a quick post about making powders,
I found this video by chance and thought it may be of some interest,
Rock Disaggregator
Perhaps one can build a system like this, much smaller of course, and get good results powdering materials. Worth a try?
