| titleOfInvention | The method that reaction in-situ prepares the ultra-temperature ceramic-based composite material of nitrogen boron |
| abstract | The invention belongs to superhigh temperature ceramics field, specially a kind of method of the ultra-temperature ceramic-based composite material of reaction in-situ preparation nitrogen boron.Raw material is mixed by zirconium boride or hafnium boride powder, silicon nitride powder and graphite powder, and reaction in-situ hot pressed sintering is carried out in hot pressing furnace or carries out reaction-sintered in discharge plasma sintering furnace.In a nitrogen atmosphere, heating rate is 10~100 DEG C/min, and sintering temperature is 1800 DEG C~2100 DEG C, and sintering time is 10 minutes~2 hours, and sintering pressure is 20MPa~40MPa.To, BN phase is uniformly introduced into superhigh temperature ceramics matrix by the method for reaction in-situ, it finally obtains ZrN (HfN)-SiC-BN composite material or ZrC (HfC)-SiC-BN composite material, the composite material can be used as the candidate material of the high-temperature-resistant structures elements such as the jet pipe throat lining of solid propellant rocket, the nose cone of jet vane and super speed vehicle, end, nose of wing. |
