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, basic performance studies of graphite, and fundamental 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.

ALevel The cracking surface shows no signs of delamination, and the inlay angle is0.5° +/- 0.1°. The lateral grain size is typically on the order of several micrometers to over ten micrometers.AThe level can reach around ten micrometers, with a longitudinal grain size of approximately several tens of nanometers. This level represents a **degree of ordered product, generally used for instrument calibration or special scientific experiments. It can also be processed through scientific research to obtain single-crystal graphene samples.

BLevel Each highly oriented pyrolytic graphite (HOPG) block available15-20fragments, with an inlay angle of0.8° +/- 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. This is suitable for most scientific research fields and is 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 ladder are slightly wavy, making it easier to secure the sample (providing better adhesion).

CLevel Inlaid horn> 1.5°. It is applicable to 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 cost, it is suitable for student experiments.
