Technical Field

[0001] The utility model relates to the technical field of ZrN preparation, in particular to a ZrN plasma preparation system. Background Art

[0002] ZrN is zirconium nitride. During its preparation, it is generally prepared by plasma. Due to the high temperature and high power density characteristics, plasma has incomparable advantages as a heat source in some special occasions.

[0014] Preferably, the water inlet pipe and the air duct are both made of soft pipes;

[0015] Among them, the arrangement of the water inlet pipe and the air duct can ensure the flexibility of the plasma torch in adjusting up and down, so as to facilitate the taking and discharging of the reactants inside the graphite crucible and ensure the normal ZrN preparation work.

[0016] Preferably, the right frame plate is a U-shaped frame, a hydraulic pump group is fixedly installed at the bottom of the inner side of the right frame plate, and a clamp is fixedly connected to the bottom end of the hydraulic pump group;

Meanwhile, the arrangement of the cooling water pump and the air cooling pump can achieve both water cooling and air cooling of the plasma torch, thus solving the problem that the poor heat dissipation effect of the plasma torch in the existing preparation process may affect the subsequent preparation efficiency;

[0021] 2.
