Product Description

[Hafnium rod ] Introduction :
We specializes in producing Hafnium as rolled sheets in various thicknesses and sizes. Most sheets are produced from cast ingots for use in coating and thin film Chemical Vapor Deposition (CVD) and Physical Vapor Deposition (PVD) processes including Thermal and Electron Beam (E-Beam) Evaporation, Low Temperature Organic Evaporation, Atomic Layer Deposition (ALD), Organometallic and Chemical Vapor Deposition (MOCVD) for specific applications such as fuel cells and solar energy. Thickness can range from 0.04" to 0.25" for all metals. Materials are produced using crystallization, solid state and other ultra high purification processes such as sublimation. American Elements specializes in producing custom compositions for commercial and research applications and for new proprietary technologies. American Elements also casts any of the rare earth metals and most other advanced materials into rod, bar, or plate form, as well as other machined shapes and through other processes such as nanoparticles and in the form of solutions and organometallics. We also produce Hafnium as rods, powder and plates. Other shapes are available by request.

[Hafnium rod ]Application:

widely used in coating processing industries

a: architectural glass, car using glass, graphic display field.

b:electronic and semiconductor field.

c:decoration and mould field.

d:optics coating materials

1, It is useful because it is easy to emit electrons (such as a filament used as an incandescent lamp). Used as a cathode of an X-ray tube, an alloy of tantalum and tungsten or molybdenum is used as an electrode of a high voltage discharge tube. Often used as a cathode and tungsten wire manufacturing industry for X-rays.

2, Pure tantalum has plasticity, easy processing, high temperature and corrosion resistance, and is an important material in the atomic energy industry. The thermal neutron capture cross section of the crucible is an ideal neutron absorber, which can be used as a control rod and protection device for the atomic reactor.

3, The Hafnium Element is also used in the latest intel45 nano processor. Due to the manufacturability of silicon dioxide (SiO2) and the reduced thickness to continuously improve transistor performance, processor manufacturers have used silicon dioxide as the material for the gate dielectric.

High Hard texture

Low impurity content

Better heat dissipation

High Tensile strength

[Hafnium rod ]Advantage:

Hafnium has high melting point and coexist with zirconium, used as cathode of X-ray tube. Hafnium tungsten or hafnium molybdenum alloy is used as electrodes of high-pressure discharge tube. Hafnium can be used as getter of many inflation systems. The hafnium getter can remove oxygen, nitrogen and other needless gases existing in the system. Hafnium is also used for nuclear reactor control rods.
