Pyrolytic Graphite Product Line — Vitreous Carbon Substrate Physical Properties of PYROID®
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 3000°C
The material is extremely anisotropic, meaning it conducts heat and electricity in the a-b plane like cooper 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 cooper 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.
Pyroid® is trade mark name of MINTEQ 10
