Diffraction standard

Last updated

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. [1] A range of materials may be used including quartz or silicon crystals. [2] There are also reports of crystals of silver behenate or silver stearate having been used for this purpose. [3] [4]
