FAQ

Q: What makes hafnium material unique?

A: Hafnium material is remarkably corrosion-resistant and an excellent absorber of neutrons, allowing its use in nuclear submarines and nuclear reactor control rods, a critical technology used to maintain fission reactions. Control rods keep the fission chain reaction active but also prevent it from accelerating beyond control.

Q: What is hafnium classification?

A: Hafnium is a chemical element with symbol Hf and atomic number 72. Classified as a transition metal, Hafnium is a solid at room temperature.

Q: Does hafnium conduct electricity?

A: Hafnium is an ideal material for this negative electrode due to its high melting point, stability and ability to conduct electricity.

Q: What are the warnings for hafnium?

A: Possibility of Hazardous Reactions: Hafnium fines will burn when exposed to an ignition source. Dust dispersed in air may be explosive. Keep fine turnings completely dry, or very wet. If wet, the water content should be more than 25% by weight for maximum safety in handling.

Q: What is hafnium commonly used for?

A: Hafnium is a good absorber of neutrons and is used to make control rods, such as those found in nuclear submarines. It also has a very high melting point and because of this is used in plasma welding torches. Hafnium has been successfully alloyed with several metals including iron, titanium and niobium.

Q: Does hafnium material oxidize?

A: Above 800°C, the oxidation rate for hafnium claddings follows a cubic to quartic law and the effective activation energy was determined in the temperature range 800-1100°C. These tests highlighted the influence of the surface conditions on the oxidation rate of hafnium in steam.

Q: Is hafnium material shiny or dull?

A: A shiny, silvery metal that resists corrosion and can be drawn into wires. Hafnium is a good absorber of neutrons and is used to make control rods, such as those found in nuclear submarines.
