About Nano Hf Hafnium Powder:
Element Hafnium Hf on the periodic table: Group 4, Atomic Number 72, d-block, Mass 178.486.
Hafnium is a shiny, silvery, malleable metal. It is resistant to corrosion because it forms a tough, impenetrable oxide film on its surface. Hafnium metal is not affected by bases and acids, except hydrofluoric acids. Hafnium element is difficult to separate from its fourth group partner zirconium because the two elements have the same atomic size.
Hafnium powder is a light gray dry metallic powder. The dry powder reacts with water to produce hydrogen, a flammable gas. The reaction may produce enough heat to ignite hydrogen.

Found in all zirconium-bearing minerals, hafnium is a ductile metal with a bright silvery luster. It is powerful and extremely resistant to corrosion. Zirconium and hafnium have almost identical chemical properties (except that hafnium is twice as dense as zirconium), making it difficult to separate. Hafnium properties are significantly affected by zirconium impurities.

Product properties of hafnium powder:
It ensures good anti-corrosive property, it is not susceptible to the erosion of acid and alkali solution, soluble in hydrofluoric acid to form a fluoride complex. At high temperature, hafnium can be directly combined with oxygen, nitrogen and other gases to form the oxide and nitride; Hafnium is stable in the air, powdered hafnium is easy to burn; the capture cross-section of hafnium thermal neutron is large, hafnium with prominent nuclear power, it is indispensable rare materials to develop the atomic energy industry.

How is Nano Hafnium Hf Powder produced?
The invention relates to a superfine high purity hafnium powder and a preparation method thereof.
Preparation includes:
1..The hafnium oxide powder and reducing agent powder with a molar ratio of 1:1 to 1:6 were mixed evenly and packed into the crucible.
2. Put the crucible into the reaction tank, cover it and vacuum it, then fill it with argon for washing, heating and reduction, and then conduct constant temperature and insulation reduction;
3. Vacuum is then pumped, and then argon is added to cool it under the protection of argon;
4 washing: the first use of pickling, and then use deionized water washing, the product will be screened, drying, that is, ultra-fine high purity hafnium powder.

Nano Hafnium Use:
Hafnium powder is mainly used in the production of hafnium alloy materials like hafnium sputtering target, because hafnium has rapid heat absorption and exothermal properties (1 times faster than zirconium and titanium), and can be made into the structural materials of jet engines and missiles.

The hafnium refractory makes it useful as a turbojet aircraft blade for freezing point pressure jet engines. Hafnium powder can also be used in the manufacture of valves, nozzles and other high-temperature components.

Most of the hafnium produced is used to make control rods for nuclear reactors.
Hafnium is used in the manufacture of iron, titanium, niobium, tantalum, and other metal alloys. One alloy used in liquid rocket thruster nozzles, such as the main engine of the Apollo lunar module, is C103, which consists of 89 percent niobium, 10 percent hafnium and 1 percent titanium.

Because of its heat resistance and affinity to oxygen and nitrogen, hafnium is a good scavenger of oxygen and nitrogen in inflatable lamps and incandescent lamps. Hafnium is also used as an electrode for plasma cutting because of its ability to release electrons into the air.

Storage Condition of Hafnium Hf Powder:
The damp reunion will affect Hf powder dispersion performance and using effects, therefore, Hafnium Hf Powder should be sealed in vacuum packing and stored in cool and dry room, the Hafnium Hf Powder can not be exposure to air. In addition, the Hf powder should be avoided under stress.

Packaging of hafnium powder:
1)high strength wooden case: the bags lined with double-layer plastic pressurized sealing, 50 kg/wooden case.
2)If the customers have special packaging requirements, we can pack the goods according to customers' requirements.
