Elemental Analysis - Hafnium (Hf)

Hafnium is a shiny silvery metal that resists corrosion and can be drawn into wires. Hafnium is a good neutron absorber and is used to make control rods found in nuclear submarines. It also has a very high melting point (3890 degrees) and is therefore used in plasma welding torches.

Hafnium alloys successfully with various metals such as iron, titanium and niobium. Hafnium oxide has been used as an electrical insulator in microchips, while hafnium catalysts have been used in polymerization reactions.

Hafnium has low biological toxicity. Most zirconium ores contain about 5 percent hafnium. Hafnium is difficult to separate from zirconium and is present in all ores. Hafnium is obtained by the methods used to extract zirconium. The metal is prepared by reducing hafnium tetrachloride with sodium or magnesium.

Hafnium is also used in vacuum tubes as a degassing agent that combines trace gases with and removes them from vacuum tubes.

Hafnium is highly resistant to corrosion due to the formation of an oxide film on exposed surfaces. In fact, it is not affected by any alkali and acid except water, air and hydrogen fluoride.

In the tests and analyzes carried out in our organization, which has a wide range of technological equipment, trained and experienced staff and applies the most modern methods, national and international standards and legal regulations in force are complied with. Among the numerous tests carried out in this context, there are also hafnium (Hf) testing services within the framework of elemental analysis.
