Application
This Standard Reference Material (SRM) is intended for use in calibration of diffraction line positions and line shapes determined through powder diffractometry.
Features and Benefits
A unit of SRM 660c consists of approximately 6 g of lanthanum hexaboride, LaB6, powder bottled under argon gas
Information on product description, disposal, and transportation is available in the accompanying MSDS
The enclosed NIST certificate contains details on the expiry date, warning to users, instructions for right storage and use, preparation, and analysis of the RM
Certified values and uncertainties calculated according to the method described in the ISO/JCGM Guide
Metrological traceability is to the SI unit for length (expressed as nanometers)
General description
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”.
