Dear Davide,
We often purchase 1 micrometer alumina from the following:
Metallurgical Supply Company
713-827-0700
sa...@metsuco.com
Item # ME-300-C
1.0um Al2O3 powder
~$240/5 pounds
www.metsuco.com
It is sufficient for routine internal-standard quantitative analyses
(and it is quite inexpensive), but you can evaluate it yourself.
Regards,
David

Hi
I would like to buy alumina standard to use for XRD quantitative
analysis. I looked in NIST website and it finished. Sigma-aldrich
sells it but is too expensive.
do you know other suppliers? Or other quantitative analysis standards?
Thanks
