Descrizione generale

The Standard Reference Material (SRM) was prepared from ultra-high purity, intrinsic silicon boules that were crushed and jet milled to a median particle size of 4.1μm. The resulting powder was then annealed under gettered argon at 1000 °C for two hours and bottled under argon.

Applicazioni

This SRM is intended for use as a standard for calibration of diffraction line positions and line shapes, determined through powder diffractometry.

Caratteristiche e vantaggi

  • A unit of SRM 640f consists of approximately 7.5 g of silicon powder bottled under argon.
  • Analysis of X-ray powder diffraction data indicated that the SRM material is homogeneous with respect to diffraction properties.
  • SRM 640f was bottled under argon to protect against humidity.
  • The certification data was analyzed using the FPA method with Pawley refinements as implemented in TOPAS.
  • Expiration details and storage instructions are available in the NIST certificate.
