Hafnium is a hafnium-based metal powder. One of the most common ways to produce hafnium from sponge hafnium is through dehydrogenation or hydrogenation.
Particle Size: 5-10 Mikron
More information about 3pdm Hf Hafnium Pulver:
Element Hafnium on the periodic Table Group 4, Atomic No 72, d block, Mass 178.486.
Hafnium a shiny and malleable silvery metal. The hard, incompressible oxide coating that forms on the surface of Hafnium makes it resistant to corrosion. Hafnium Metal is not affected by acids or bases except for hydrofluoric. Hafnium element can be difficult to distinguish from its fourth group member zirconium.
Hafnium is a grayish-colored dry metallic powder. This dry powder reacts well with water and produces hydrogen. It is possible for the reaction to produce enough heat that it ignites hydrogen.
It is found in all zirconium containing minerals. Hafnium can be found as a ductile, brightly silvery metal. It’s strong and highly resistant to corrosion. Zirconium (and hafnium) have nearly identical chemical properties, with the exception that zirconium is twice as dense than zirconium. This makes it hard to separate. Hafnium properties will be affected significantly by zirconium impurities.

Description and appearance of hafnium-powder:
The crystalline form of high purity hafnium also goes by the name crystalline hafnium. It is a silver-colored crystal that has a metallic luster.
hafnium powder MF: Hf
hafnium powder Molecular weight: 178.49
hafnium powder Density: 13.31 g/cm3
hafnium powder melting point: around 2227

Properties of hafnium Powder:
The metal is highly resistant to corrosion and can be easily dissolved in hydrofluoric acid, which forms a fluoride complex. Hafnium, at high temperatures, can be mixed with nitrogen, oxygen and other gases to create the oxide and the nitride.
How is 3pdm hafnium Hf Powder manufactured?
The invention is a method of preparing superfine hafnium powder with high purity.
This preparation involves:
1.. Mix the hafnium dioxide powder and reducing powder in a ratio of 1 to 6 and pack it into the crucible.
2. Place the crucible inside the reaction vessel, seal it, vacuum it, then add argon to the container for heating, washing and reduction. Then, you can conduct constant temperature or insulation reduction.
3. After vacuuming, argon is used to cool it.
4 washing: First use pickling and then deionized waters washing. The product is then screened, dried, which is ultra-fine, high purity hafnium.
3pdm Hafnium Use:
The main use of hafnium powder in hafnium alloy material production is Hafnium Sputtering Target. Because of its rapid heat absorption rate and exothermal property, hafnium can be used as a structural component for jet engines or missiles.
Hafnium is a refractory, which makes it useful for turbojet engines with freezing point pressure. Hafnium can be used for the production of valves,nozzles, or other high-temperature parts.
A majority of the produced hafnium is used in making control rods for nuclear power plants.
Hafnium is used for the production of iron, titanium (niobium), tantalum and other metal alloys. C103, which is composed of 99% niobium and 10% hafnium, is used for liquid rocket thruster tubes, as well as in the Apollo moon module’s main engine.
Due to its heat resistance, affinity to oxygen or nitrogen and high heat resistance, hafnium can be used as a good scavenger for nitrogen and oxygen in incandescent and inflatable lamps. Hafnium, which can release electrons into air, is used in plasma cutting electrodes.
Hafnium Powder Storage:
Hf powder performance and usage effects can be adversely affected by the damp reunion. Hafnium Hf Powder needs to be stored in vacuum bags and kept in a cool, dry place. Hf powder must be kept away from stress.
Package of hafnium Powder:
1) High strength wooden box: Bags lined with double-layer, plastic pressurized sealant.
2) We can package the goods to meet special packaging needs if requested by customers.
