Silicon Powder Line Position Standard

Calibrates the diffractometer's 2-theta scale, run alone or mixed into a sample, so the lattice parameters of a new phase can be trusted. Certified lattice parameter with a stated uncertainty, for SRM 640g a = 0.5431144 nm at 22.5 °C with an expanded uncertainty of 0.000008 nm.
