Our Pyroid® pyrolytic graphite is a very light weight, 5'9's pure, solid crystal composition, with no granular components, extremely smooth surface, capable of withstanding cryogenic temperatures as well as temperatures in excess of 3,000°C
The material is extremely anisotropic, meaning it conducts heat and electricity in the a-b plane like copper but acts like a ceramic in the normal direction. In an annealed state, the thermal and conduction properties increase up to four to eight times that of aluminum and copper respectively.
The material has zero porosity making it extremely stable and exhibits no outgassing. It is ideal for use in corrosive environments including acids and chlorine, and is highly transparent to organic samples and electrons, for analytical work, such as x-ray investigation, metallurgical, crystal growth, medical imaging technology etc.
