R: Alumina standard for quantitative analysis

[Marco Taddei]

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).

davide, you can look the same dealers for neutron diffraction as well, or maybe 
some colleague can borrow some. (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

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
