Pyrolytic Graphite
Pyrolytic graphite is a synthetic material known for its high thermal conductivity and unique anisotropic properties. It's produced through a process called chemical vapor deposition (CVD), where hydrocarbon gas is decomposed at high temperatures in a vacuum on a substrate, allowing the graphite to be deposited layer by layer. This results in a material with highly oriented graphite crystals.
Product Info
Thermal conductivity in pyrolytic graphite is significantly higher in the plane parallel to the deposition layer, making it one of the most effective conductors of heat in-plane and a good insulator out-of-plane. This distinct thermal behavior can be exploited in applications requiring efficient heat dissipation across a surface.
Application
1. Electronics Cooling: Pyrolytic graphite sheets are used to manage heat in various electronic devices, including smartphones, LEDs, and high-power transistors.
2. Construction of Grid Structures: Used in some high power vacuum lamps.
3. High Temperature Applications: Such as heat shields, laboratory furnaces.
4. Graphite-Reinforced Plastic: Used in the construction of this material.
