Hafnium Crystal Bar

Product Information

Hafnium Crystal Bar is made of a high purity form of hafnium. It has almost the same chemical properties as zirconium, including corrosion-resistant. Hf is rare and has a larger density compared with zirconium and people are developing methods to separate them by density.

Hafnium crystal bars have a shiny appearance and sometimes are bought as element collections. The light blue color of hafnium crystal bars makes them different from zirconium crystal bars. ATT is a global supplier of High Purity Hafnium and we can provide customized Hafnium products. High Purity Hafnium is a silvery metal and get from High Purity hafnium (Hf) Crystal Bar. High-purity Hafnium Crystal Rods are produced by the iodination method and electron-beam smelting. The purity can be Hf+Zr≥99.99%, Zr≤0.2%/0.3%/0.5%, with low zirconium (200ppm, or 0.025%). Mainly used in the production of hafnium-based alloy materials. We provide customized High Purity Hafnium Crystal Bars with the shortest lead time and the best price.

Hafnium Crystal Bar Applications:

It is widely used in the semiconductor coating, the optical coating, the plasma cutting, the metallic glass and other fields.

Used in control rods in the nuclear reactors due to its strong ability to capture neutron

Used for producing super alloys

Used in rocket propeller

Used as cathode in X-ray tube

Hafnium alloy can be used as prototype of rocket nozzle

High-purity hafnium crystalline rods are used in nickel-based high-temperature alloy additives, CVD evaporation coating, and other industries. Also used in the field of atomic energy, or in military applications.

It is mainly used to produce hafnium-based alloy materials. Because hafnium has fast heat absorption and heat release properties (1 time faster than zirconium and titanium), it can be used as structural materials for jet engines and missiles.

The refractory properties of hafnium allow it to be used as a blade for turbojet aircraft and in freezing-point pressure jet engines. It can also be used to make valves, nozzles, and other high-temperature parts
