Description
This Standard Reference Material (SRM®) consists of two powders intended for quantitative analysis of the alpha and beta polymorphs of silicon nitride via powder diffraction methods. The powders are combinations of the alpha and beta polymorphs, one is high in the alpha phase content (alpha 656), while the other contains a larger amount of the beta polymorph (beta 656). This selection allows the user to choose the powder which is optimal for their specific analysis. A unit of NIST-656 consists of approximately 10 g of each powder. /// Sample value(s) - please ask for current certificate.

NIST provides over 1300 Standard Reference Materials® as well as articles and practice guides describing the development, analysis and use of SRMs.
NIST Standard Reference Materials are used by analytical laboratories in industry, academia and government in order to facilitate commerce and trade and to advance research and development. The SRMs are produced by the engineering laboratory, the material measurement laboratory, and the physical measurement laboratory at NIST. They are available for chemical composition, physical properties, and engineering materials.
