    Product Description

    Hafnium powder is a silver-white metal, in terms of physical properties, hafnium powder has a high melting point and a high boiling point, its melting point is 2545 ° C, the boiling point is 3876 ° C. It also has high thermal conductivity and high resistivity, so it is often used in the manufacture of superalloys and electronic components. In terms of chemical properties, hafnium powder is easy to react with non-metallic elements such as oxygen and nitrogen to generate corresponding oxides and nitrides. It also forms alloys with many metals, such as hafnium-based alloys. In terms of use and importance, hafnium powder is a very important material, widely used in aerospace, military, electronics and other fields. For example, it is synthesized with tungsten, rhenium and other metals into high-strength, high-temperature resistant hafnium-based alloys for the manufacture of aircraft engines and rocket engines. In addition, hafnium powder can also be used to manufacture electronic components, such as capacitors, resistors, etc.

    Hafnium Hf powder mainly used for:

    1. Commonly used in X-ray cathode and tungsten wire manufacturing;

    2. Pure hafnium has the advantages of plasticity, easy processing and high temperature corrosion resistance, and is an important material in the atomic energy industry;

    3. Hafnium has a large thermal neutron capture section, making it an ideal neutron absorber, which can be used as a control rod and protective device in atomic reactors;

    4. Hafnium powder can be used as propellant for rockets

    5. Hafnium can be used as a getter for many inflatable systems. Hafnium getter can remove oxygen, nitrogen and other unnecessary gases present in the system;

    6. Hafnium is often used as an additive in hydraulic oil to prevent the volatilization of hydraulic oil during high-risk operations. As Hafnium has strong anti-volatility, it is generally used in industrial hydraulic oil and medical hydraulic oil;

    7. Hafnium element is also used in the latest Intel45nm processor;

    8. Hafnium alloys can be used as front protective coating for rocket nozzles and gliding re-entry vehicles, and Hf-Ta alloys can be used to manufacture tool steels and resistance materials. Hafnium is used as an additive element in heat-resistant alloys, such as alloys of tungsten, molybdenum, and tantalum. HfC can be used as a cemented carbide additive due to its high hardness and melting point.
