Highly Oriented Pyrolytic Graphite/HOPG
BZNCarbon supplies high-purity Highly Oriented Pyrolytic Graphite (HOPG)—a specialized synthetic graphite material manufactured through high-temperature chemical vapor deposition and graphitization processes. HOPG exhibits properties very close to single-crystal graphite and is recognized for its exceptional structural orientation and anisotropy.
Description
What is HOPG?
Highly Oriented Pyrolytic Graphite is a form of synthetic graphite with extremely low mosaic spread and very high thermal and electrical conductivity in the a–b plane. It is used as a reference standard in advanced material research and high-tech industrial applications due to its excellent crystallinity and purity.
Applications:
Scanning Probe Microscopy (AFM, STM calibration)
Neutron monochromators and analyzers
X-ray diffraction calibration
Surface science and crystallography
Electron microscopy reference samples
Nano- and quantum-scale experiments
Energy storage and graphene research
Grades Available:
Grade A: Mosaic spread ~0.5° ± 0.1° (FWHM) – Highest crystallinity
Grade B: Mosaic spread ~0.8° ± 0.2° (FWHM) – Standard laboratory use
