>From Y2O3 annealed at around 1200 degC, and using fundamental parameters peak fitting in XFIT (BGMN and Topas are currently maintained programs), I get around 3300 Angstrom for crystallite size - and near zero strain (using the size/strain modelling defaults in XFIT). Though don't have a comparison with LaB6. What is the certificate crystallite size and strain value for NIST LaB6 - via Google, the NIST website seems to be giving a problem finding this out? http://ois.nist.gov/srmcatalog/certificates/view_cert2pdf.cfm?certificate=660a Error Occurred While Processing Request Error Diagnostic Information An error has occurred.
