Highly oriented pyrolytic graphite (HOPG) is a highly pure and ordered form of synthetic graphite. It is characterised by a low mosaic spread angle, meaning that the individual graphite crystallites are well aligned with each other. The best HOPG samples have mosaic spreads of less than 1 degree. Note that … See more The method used to produce HOPG is based on the process used to make pyrolytic graphite, but with additional tensile stress in the basal-plane direction. This produces improved alignment of the graphite crystallites … See more HOPG is used in x-ray optics as a monochromator and in scanning probe microscopy as a substrate and for magnification calibration. See more WebThe high-oriented pyrolytic graphite is highly resistant to heat, light, and mechanical shocks. HOPG is an extremely pure and highly ordered form of graphite. Its impurities are less …
