The main purpose is to produce hafnium nuclear reactor control rods. Pure hafnium has plasticity, easy processing, high temperature corrosion resistance, is an important material for atomic energy industry. Large thermal neutron capture cross section of hafnium is more ambitious neutron absorber control rods and can be used for protection of the nuclear reactor. It can be used for rocket propulsion. The cathode of an X-ray tube can be fabricated in the electrical industry. Hafnium alloy, and can be used for rocket nozzles aircraft gliding reentry leading edge protective layer, Hf-Ta alloy tool steel and can be fabricated of resistive material. In heat resistant alloy of hafnium is used as add elements, such as tungsten, molybdenum, tantalum alloys Some of hafnium increases. Because of the high melting point and hardness HfC, increasing agent can be used as carbide. 4TaC • HfC a melting point of about 4215 ℃, the highest known melting point of the compound.
