Hafnium Metal

About Hafnium Metal

Symbol: Hf
Atomic Number: 72
Atomic Mass: 178.49
Element Category: Transition Metal
Hafnium is a ductile metal. It has an oxide layer on its surface that prevents corrosion. The oxide composition is chemically similar to that of zirconium.
Hafnium absorbs neutrons and is used in control rods in nuclear reactors. Its melting point is high, and it resists corrosion. Consequently, hafnium is utilised in high‑temperature alloys and ceramics.

The physical properties of hafnium are affected by impurities from zirconium. These elements occur in zirconium ores in an approximate ratio of 50 to 1. Given their chemical similarity, separation is difficult. The hafnium metal products from SAM are over 99.50% pure.

Stanford Advanced Materials (SAM) can now provide various hafnium metal products, including:

Application of Hafnium Metal

- Given that hafnium can emit electrons into the air and has a high melting point, it is used in the electrodes for plasma cutting.
- Hafnium captures neutrons and is used in nuclear reactor control rods.
- Hafnium is employed as an additive in alloys.
- Recently, scientists at Intel and IBM found that hafnium‑based compounds can be utilised in gate insulators to reduce processor dimensions.
- Hafnium wires and other Hf components are used in plasma cutting because they are capable of electron emission into the air.
- They are used to control the recrystallisation of tungsten filaments.
