Welcome and nice to meet you.
I can borrow you some Lab6 NIST 660c standard reference.
Best regards,

Another option could be to prepare the standard in-house. This paper: J. Appl.

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
