Other information

HOPG(Highly Oriented Pyrolytic Graphite) is a new type of high-purity carbon material, produced through high-temperature and high-pressure treatment of pyrolytic graphite, with properties approaching those of single-crystal graphite. Its main applications include X-ray monochromators, neutron filters and monochromators, fundamental research on graphite properties, and basic studies of large-scale graphite intercalation compounds, providing microscopists with a reusable smooth surface. Unlike mica, Highly Oriented Pyrolytic Graphite (HOPG) is completely non-polar, making it suitable for elemental analysis, with only carbon atomic background signals in the analytical signal. The excellent surface smoothness of Highly Oriented Pyrolytic Graphite (HOPG) 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.Applicable to most scientific research fields, 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 > 1.5° for bevel angle. 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 price, it is suitable for student experiments.
