In crystallography, mosaicity is a measure of the spread of crystal plane orientations. A mosaic crystal is an idealized model of an imperfect crystal, imagined to consist of numerous small perfect crystals (crystallites) that are to some extent randomly misoriented. Empirically, mosaicities can be determined by … See more An important application of mosaic crystals is in monochromators for x-ray and neutron radiation. The mosaicity enhances the reflected flux, and allows for some phase-space transformation. Pyrolitic graphite (PG) … See more To describe diffraction by a thick mosaic crystal, it is usually assumed that the constituent crystallites are so thin that each of them … See more WebThe mosaic crystal is a simplified model of real crystals proposed by C.
