I am looking for polycrystalline high purity aluminium (at least 99.99%) with crystallite size of as large as possible. I would like to investigate phenomenons at the grain boundaries. It would be great if the grain boundaries reached 1 mm while the external surface of the aluminium piece 100 sq. cm.
Could you please propose any Company or University who produces this kind of material or undertakes to manufacture such a product within the framework an agency contract?
Thank You in advance.
Have a nice day!
Dear Dr. Andrea Domán,
I suggest you to have a look at the following “specific” sellers:

Best regards, Pierluigi Traverso.

See carefully the actual chemistry.
The better purity the higher grain size.
Hence, Al99.9999 may have macro grains visible unarmed far larger 1 mm.
Good luck
I wish you all a happy holiday season with peace in mine, harmony with the surrounding, and progress in life for the best of man kinds.
Hi Andrea,
You may make an inquiry at Alfa Chemistry, they offer you advices and kinds of good-quality materials.
