詳細

詳細

The SRM was prepared in a dedicated processing run using the ¹¹B isotope enriched to a nominal 99 % concentration. This isotopic enrichment renders this SRM relevant to the neutron diffraction community. The resulting powder was then annealed and bottled under argon. Certification was performed using data from a NIST-built diffractometer, with analyses via the fundamental parameters approach (FPA) using the Rietveld method. The certification of SRM 660c is valid indefinitely, provided the SRM is handled and stored in accordance with the instructions given in the “Instructions for Storage and Use”.

For more information, please refer to the COA and SDS.
