Product Description:

The certified values delivered by this Standard Reference Material (SRM) are intended for the calibration of powder diffraction equipment with respect to line position and profile breadth as a function of 20 angle. A unit of SRM 640g consists of approximately 7.5 g of silicon powder bottled under argon.

Product Information:

SKU: 640g
Availability: Available for Purchase
Valid until: Indefinite
Unit of Issue: 7.5 g
Unit Description: A unit of SRM 640g consists of approximately 7.5 g of silicon powder bottled under argon.
Storage: SRM 640g was bottled under argon to protect against humidity. When not in use, store the unused portion of this powder tightly capped in the original bottle or in a manner with similar or greater protection against humidity. 

Use: The loading of samples for Bragg-Brentano diffractometers should be performed so as to achieve a powder bed of a high packing density and a flat surface. 

STABILITY AND REACTIVITY:

• Reactivity: Stable at normal temperatures and pressure.
• Possible Hazardous Reactions: Dust/air mixtures may ignite or explode.
• Conditions to Avoid: Avoid generating dust. Avoid heat, flames, sparks or other sources of ignition.
• Incompatible Materials: Acids, halogens, metal carbide, metal salts, metals, oxidizing materials.
