Graphite thermal decomposition
WebJul 22, 2024 · While the preliminary test did confirm steady-state decomposition of nitrous oxide within the heat exchanger, further tests resulted in temperatures exceeding the melting point of copper within the disks. The last heat exchanger was a set of stainless-steel disks of the same design. WebPGS(Pyrolytic Highly Oriented Graphite Sheet) is made of graphite with a structure that is close to a single crystal, which is achieved by the heat decomposition of polymeric film. PGS is a competitive conductive sheet with high thermal conductivity and high flexibility. c axis a-b plane 3.354~3.356 x 10-8cm
