Applications
HfC can form solid solution with many compounds as ZrC, TaC and so on. For example HfC-4TaC complex carbide that is disphase from microscopic strucutre. One phase is HfC-TaC eutectic. The other phase is needle-like free graphite phase of shape ratio 50:1. This near eutectic HfC products own good thermostability and high melting point, which can use in laryngeal material of rocket nozzle
