Another option could be to prepare the standard in-house. This paper: J. Appl. Cryst. (2014). 47, 136–145 describes an annealing procedure to produce Al2O3 with a very low amorphous content (even lower than the NIST standard).

(First guess) The other thing, if you are trying to reproduce data is to ask the people who performed it (and published in journal) to send you some quantity (second guess). Ask NIST if they can direct you to some other dealer (Third guess). I would ask X - Ray diffraction instrument builders as they normally have it to calibrate their instruments. (Fourth guess). I hope some of these can be of help El 23/01/2018 07:07, "Davide Levy" <davide.lev...@gmail.com<mailto:davide.lev...@gmail.com>> escribió: 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?
