It is mainly for the production of hafnium alloy material, because hafnium has fast endothermic
and exothermic performance ( 1 times faster than zirconium and titanium) , thus it can be made
the structural material of jet engines and missiles. The refractory of hafnium, making it can be used
as the turbojet aircraft vane, used in freezing the point pressure jet engine. Also can be used to
make valve, nozzle and other high temperature parts.
