Other information

HOPG（Highly Oriented Pyrolytic Graphite) is a new type of high-purity carbon material.,It is a new type of graphite material produced by treating pyrolytic graphite under high temperature and high pressure, with properties close to those of single-crystal graphite. Its main applications includeXRay monochromators, neutron filters and monochromators, fundamental performance studies of graphite, and basic research on large-scale graphite intercalation compounds provide microscopists with a reusable smooth surface. Unlike mica, highly oriented pyrolytic graphite (HOPG) Completely non-polar, suitable for elemental analysis, with only carbon atomic background signals in the analytical signal. Highly oriented pyrolytic graphite (HOPG) Its excellent surface smoothness allows it to serve as a blank background.

AThe fracture surface shows no signs of delamination, and the mosaic angle is 0.5° +/- 0.1°.The lateral grain size is typically on the order of several micrometers to over ten micrometers.Among them, Grade A can reach about ten micrometers, with a longitudinal grain size of approximately several tens of nanometers.。This level is a **highly ordered product**.Generally used for instrument calibration or special scientific research experiments, it can also be processed through scientific research to obtain single-crystal graphene samples.

BEach highly oriented pyrolytic graphite (HOPG) block can yield 15-20 cleaved pieces, with a mosaic angle of 0.8° +/- 0.2°.The lateral grain size is typically on the order of several micrometers to over ten micrometers, while the longitudinal grain size is around ten nanometers.It is applicable to most scientific research fields and easy to repair and update.ACompared to the grade, some users prefer this type of highly oriented pyrolytic graphite (HOPG), because the lobes of the steps are slightly wavy, making the sample easier to fix (with better adhesion).

CLevel > 1.5° for the bevel angle. Suitable for most scientific research fields.The lateral grain size is typically on the order of several micrometers to over ten micrometers, while the longitudinal grain size is around a few nanometers.However, due to its low price, it is suitable for student experiments.
