Description
Overview
Hafnium, a lustrous, silvery transition metal, boasts an impressive melting point of 2,233°C, making it ideal for extreme conditions. Typically processed into ingots, rods, or powder, it is extracted as a byproduct of zirconium refining due to their chemical similarity. Prized for its neutron absorption and excellent corrosion resistance, hafnium is essential in nuclear reactors as control rods and in high-temperature alloys for aerospace applications, such as jet engines. Its durability and specialized uses in demanding industries, along with its potential for recycling, highlight hafnium’s role as a vital material in the technology metals market.
Properties
- Composition: Typically 99.9% or higher pure praseodymium.
- Density: 6.77 g/cm³.
- Melting Point: 935°C (1,715°F).
- Color: Silvery-white, metallic, and lustrous (tarnishes rapidly in air).
- Malleability: Moderately malleable, can be shaped with effort.
- Ductility: Limited ductility, can be drawn into wires with processing.
- Electrical Conductivity: Poor conductor, resistivity ~68 μΩ·cm at 20°C.
- Thermal Conductivity: Low, ~12.5 W/(m·K) at 20°C.
- Corrosion Resistance: Highly reactive, oxidizes quickly in air; reacts with acids and water.
Applications
- Nuclear reactors (e.g., control rods)
- Superalloys for aerospace (e.g., jet engine components)
- Plasma cutting (e.g., electrodes)
- Optical coatings (e.g., hafnium oxide for UV lenses)
