Pyrolytic Graphite Plates
BZNCarbon supplies high-purity pyrolytic graphite plates with stable and reliable quality. We offer both PG grade and HOPG grade pyrolytic graphite products in the form of plates and boards.
Description
Pyrolytic graphite is an advanced carbon material produced through chemical vapor deposition of hydrocarbon gases at 1800–2000 °C under controlled pressure. This process results in highly oriented crystalline layers, giving the material excellent anisotropic properties such as superior thermal and electrical conductivity in the AB plane, while offering high mechanical strength and extremely low impurity levels (as low as 0.0002%).
Pyrolytic graphite maintains structural integrity under high temperatures, up to 1800 °C in a vacuum of 10 mmHg, making it ideal for extreme conditions.
Typical Applications
Semiconductor heat spreaders
Nuclear reactor shielding
Aerospace insulation and radiation barriers
Advanced thermal management in electronics
X-ray and neutron monochromators
Magnetic levitation and sensor substrates
