Hafnium Powder Applications

  • Nuclear Industry: Hafnium powder is used in nuclear reactors to make fuel casing materials and control rods.
  • Alloy Manufacturing: Hafnium powder can manufacture high-temperature and high-strength alloys to enhance the alloy’s high-temperature resistance, oxidation resistance, and corrosion resistance.
  • Electronic Components: Hafnium powders produce thin film coatings in electronic components.
  • Spraying and Coating: Hafnium powders can be used for high-temperature spraying and as a coating material to improve the oxidation and wear resistance of metal surfaces.
  • Catalysts and Chemical Reactions: Hafnium powders are used as catalysts or catalyst carriers in petrochemical and other chemical reaction processes.

Hafnium Powder Packaging

The Hafnium Powder is carefully placed in wooden cases or cartons with additional support from soft materials to prevent any shifting during transportation. This packaging method guarantees the integrity of the products throughout the delivery process.
