Hi all,
This is to indicate that NIST SRMs 640c, silicon powder, and 660a,
lanthanum hexaboride powder, are available from the NIST SRM Program sales
office. These SRMs are certified with respect to lattice parameter at the
part-per-million level. Considerable effort has been expended to tailor
the microstructure of these SRMs to exhibit a minimal level of particle
size and micro-strain induced profile broadening.
Please see:
http://ois.nist.gov/srmcatalog/certificates/view_cert2gif.cfm?certificate=640c
and
http://ois.nist.gov/srmcatalog/certificates/view_cert2gif.cfm?certificate=660a
for views of the certificates which offer a description of the material and
the certification method.
Regards,
Jim
