    Pyrolytic graphite crucible

    Pyrolytic graphite crucible is different from general graphite crucible. It is made of carbon atoms deposited on the model directionally after cracking of hydrocarbons in high temperature, low pressure and nitrogen atmosphere, and then demoulded after cooling. Description The crucible has good heat conduction, conductivity and mechanical strength. The wall of the device is smooth, compact, with little permeability, easy to clean and decontaminate, high temperature resistance and strong c...

    Pyrolytic graphite is a new type of carbon material. It is a kind of pyrolytic carbon with high crystal orientation, which is deposited by high-purity hydrocarbon gas on the graphite substrate at 1800 ℃ ~ 2000 ℃ under a certain furnace pressure. It has high density (2.20g / cm), high purity (impurity content (0.0002%) and anisotropy of thermal, electrical, magnetic and mechanical properties. The vacuum of 10mmHg can still be maintained at 1800 ℃.

    Because the blanks need to be processed and meshed to grid, there are special requirements for pyrolytic graphite grid blanks: small residual stress, no stratification, no obvious rumen, good processing and meshing performance. Pyrolytic graphite grid can effectively reduce the volume of the electron tube, improve the reliability of the emission tube, and extend the service life, especially for the development of large power emission tube and UHF electron tube.
