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

Hafnium Nanopowder:
Hafnium Hafnium on the periodic table : Group 4, Atomic Number 78, d-block Mass 178.486.
Hafnium consists of a malleable, shiny metal. It's resistant to corrosion due to the tough oxide layer that forms on its surface. Hafnium metallicis unaffected by acids or bases except hydrofluoric. Hafnium element 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.

Appearance of hafnium and its description:
It is a silvery metal crystal that has a metallic shine.
hafnium powder MF: Hf
hafnium powder Molecular weight: 178.49
hafnium powder Density: 13.31 g/cm3
Hafnium powder Melting temperature: around 2227
Hafnium powder Boiling points: about 4602

Product characteristics of hafnium:
It is highly anti-corrosive, resistant to acid and alkali erosion, and soluble in Hydrofluoric Acid to form fluoride complex. Hafnium at high temperature can be directly combined to oxygen, nitrogen, other gases, to form the oxide, and nitride. Hafnium in the air is stable, powdered Hafnium easily burns.

How are Nano Hafnium Powder manufactured?
The invention relates a superfine, high purity hafnium and a method for preparing it.
Prepare:
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 the furnace 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 waters washing. The product is then screened before drying.

Nano Hafnium Use:
Hafnium powder can be used to produce hafnium-alloy materials such as hafnium targets. It has high heat absorption properties and is exothermic (1 times faster that zirconium, titanium and other alloys).

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

Hafnium rods are used for the majority of nuclear reactor control rods.
Hafnium alloys are used to manufacture iron, tantalum (niobium), and titanium. C103 alloy is used for liquid rocket thruster nodes, like the main engine in the Apollo lunar module. C103 consists of 89 % niobium and 10 % hafnium.

Hafnium, because of its high heat resistance and affinity with oxygen and nitrogen is an excellent scavenger for oxygen and nitrogen. It can be used in both incandescent lights and inflatable lamps. 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.
