Diffraction standard
In crystallography, a diffraction standard, or calibration crystal, is a crystal used to calibrate an X-ray spectrometer to an absolute X-ray energy scale. Quartz or silicon crystals are typically used. There are also reports of crystals of silver behenate or silver stearate having been used for this purpose.
