“…It has been successfully used in making nozzles for rockets, combustion chambers in harsh environments at high temperature, and electrical and nuclear engineering components as grids for electronic valves or laser tube. [1][2][3] Temperature and pressure are the most dominating factors in the preparation of pyrolytic graphite. [3][4] Zhang 5 proposed a relationship between microscopic structure, density, purity and the deposition temperature.…”

To investigate the influence of deposition pressure on the texture of pyrolytic graphite, a series of experiments were carried out. The pyrolytic graphites were fabricated at 2000°C with propylene as the carbon source and nitrogen as the carrier gas in a system pressure from 1·1 to 1·8 kPa. Results show that lowering the deposition pressure will increase the density and thin the growth cones. The reduce of deposition pressure will also cause an increasing in the degree of graphitisation extracted from X-ray diffraction patterns and the value of ( IG/ ID) in Raman spectra. Therefore, lower deposition pressure is more inclined to yield high texture pyrolytic graphite. Finally, the deposition mechanism was discussed.
