Hafnium Metal Hf CAS 7440-58-6 For Control Rod Of Nuclear Reactor
Name: Hafnium metal, Hafnium wire Molecular formula: Hf
CAS: 7440-58-6 Molecular weight: 178.49
Description: Hafnium is a silvery gray transition metal with luster. It does not react with dilute hydrochloric acid, dilute sulfuric acid and strong alkali solution, but it is soluble in hydrofluoric acid and aqua regia. Hafnium has more abundances in the earth's crust than bismuth, cadmium and mercury, and is equivalent to beryllium, germanium and uranium. Hafnium is found in all zirconium bearing minerals. Hafnium mostly coexists with zirconium, and there is no separate hafnium raw material. The raw material of hafnium is crude hafnium oxide separated from the technological process of manufacturing zirconium. Hafnium oxide was extracted by ion exchange resin, and hafnium metal was prepared by magnesium reduction or thermal decomposition of hafnium tetraiodide.

Used: Pure hafnium is an important material in atomic energy industry because of its plasticity, easy processing, high temperature resistance and corrosion resistance. Hafnium is an ideal neutron absorber because of its large thermal neutron capture cross-section. It can be used as control rod and protection device of atomic reactor. Hafnium powder can be used as thruster of rocket. The cathode of X-ray tube can be made in electrical industry. Hafnium alloy can be used as the front protective layer of rocket nozzles and glider re-entry vehicles. Hafnium tantalum alloy can be used to make tool steel and resistance materials. It is used as the cathode of X-ray tube, and the alloy of hafnium and tungsten or molybdenum is used as the electrode of high-voltage discharge tube.
