High Purity Nano Hafnium Hf powder CAS 7440-58-6, 99% |

Hafnium Nanopowder:
Hafnium Hafnium on the periodic table : Group 4, Atomic Number 74, d-block Mass 178.486.
Hafnium a shiny silvery metal. It’s resistant to corrosion due to the tough, impenetrable film of oxide that forms on its surface. Hafnium metallicis unaffected by acids or bases except hydrofluoric. Hafnium can be difficult to separate because they have the same atomic sizes.
Hafnium Powder is a dry, light gray metallic powder. The dry powder reacts when it comes into contact with water, producing hydrogen. This is a flammable liquid. The reaction could produce enough heat for hydrogen to ignite.

Hafnium can be found in zirconium minerals. It is a ductile, brightly glistening metal. It is extremely strong and resistant to corrosion. Zirconium, hafnium, and their chemical properties are almost identical. (Hafnium being twice as dense than zirconium). This makes them difficult to separate. Hafnium’s properties is affected by zirconium.

Product characteristics of hafnium:
It is highly anti-corrosive, resistant to acid and alkali erosion, soluble with hydrofluoric to form fluoride complex. Hafnium at high temperature can be combined with oxygen and nitrogen to form nitride. Hafnium powder is easy to burn.

How are Nano Hafnium Powder manufactured?
The invention relates a superfine, high purity hafnium and a method for preparing it.
Preparation includes the following:
1..The hafnium dioxide powder and reducing agents powder in a molar ration of 1:1 to 1:2 were mixed evenly, and packed into crucible.
2. The crucible should be placed in the reaction vessel, covered and vacuumed, and then filled with argon to wash, heat and reduce, followed by constant temperature reduction.
3. After vacuum, argon is added for cooling under argon’s protection.
4 washing: first, pickling and then using deionized distilled water to wash the product. Then, it is screened before drying.

Nano Hafnium Use:
Hafnium powder can be used to produce hafnium-alloy materials such as hafnium-sputtering targets. It has exothermal properties and rapid heat absorption (1 times faster than titanium and zirconium), and is suitable for making structural materials in jet engines and rockets.

The hafnium refractory is useful for turbojet aircraft blades in freezing point pressure jet engine. Hafnium powder is also used to manufacture valves and nozzles as well as other high-temperature parts.

Hafnium rods are used for the majority of nuclear reactor control rods.
Hafnium alloys are used in the production of tantalum, niobium and iron. C103 alloy is used for liquid rocket thruster nodes, like the main engine in the Apollo lunar module. C103 is composed of 89 per cent niobium and 10 per cent hafnium.

Hafnium, because of its high heat resistance and affinity towards oxygen and Nitrogen, is an excellent scavenger for nitrogen and oxygen in inflatable and incandescent lights. Hafnium, which can release electrons in the air, is also used for plasma cutting.

Storage condition of Hafnium HF Powder:
Hafnium Hf Powder cannot be exposed to the air. The powder should be packed in vacuum and kept in a dry and cool room. Hf Powder should also not be exposed to stress.

Packaging hafnium:
1) High strength wooden case : bags with double-layer plastic seals, pressurized. 50 kg/wooden box.
2) If the customer has special packaging requirements we can package the goods accordingly.
