Device for preparing boron-doped isotropic pyrolytic carbon material

The utility model relates to the field of pyrolytic carbon, and particularly to a device for preparing boron-doped isotropic pyrolytic carbon material. The device is provided with a deposition device and a gas flow control system communicated with the deposition device. The deposition device is a conical graphite bed deposition device. A lower opening of the reactor is provided with a gas distribution plate. The center of the gas distribution plate is provided with a reverse conical opening. The upper end of the gas distribution plate has a screen structure. According to the utility model, a decomposition device and a gas flow control system are designed. The design realizes effective adding and uniform distribution of boron in isotropic pyrolytic carbon material, and lays a foundation for preparing the boron-doped isotropic pyrolytic carbon material with excellent property. The utility model settles the defects in the aspects of oxidation resistance, wearing resistance, high-temperature ablation resistance,
