Hafnium wire in industry application

Hafnium wire, made by metal hafnium control. In nature, hafnium and zirconium symbiosis, often containing zirconium minerals containing hafnium, hafnium and zirconium show class with like, hafnium mainly occurs in the zircon. In the industrial use of zircon HfO2 content is 0.5-2%. The beryllium zircon from secondary zirconium with HfO2 can be as high as 15%. There is a kind of metamorphic zircon SPAR, containing more than 5% of HfO2. After the two kinds of mineral reserves, less industry has not yet been adopted. In the process of hafnium mainly by the production of zirconium recycling.

Is the main purpose of hafnium nuclear reactor control rod. Pure hafnium has plasticity, easy processing, high temperature resistant corrosion, is an important material atomic energy industry. Hafnium thermal neutron capture cross section is large, is the ideal neutron absorber, atomic reactor control rod and protection devices. Hafnium powder as a rocket propulsion. In the electronics industry to make X ray tube cathode. Hafnium alloy can make the rocket nozzle and gliding of the re-entry vehicle front cover, Hf, Ta can manufacture of tool steel and alloy resistance materials. Hafnium in heat resistant alloy used to add elements, such as tungsten, molybdenum, tantalum alloy in some adding hafnium. HfC due to their high hardness and melting point, hard alloy additives. 4, tac HfC, melting point is 4215 ℃, for the melting point of the highest known compounds.
