Hafnium (Hf)

Hafnium (Hf)

Discovered in 1923, hafnium has since been alloyed with iron, titanium, niobium, tantalum, and other metals.

Hafnium is a ductile metal with a brilliant silver luster and is very difficult to separate. Resistant to concentrated alkalis, it reacts at elevated temperatures with oxygen, nitrogen, carbon, boron, sulfur, and silicon, and directly with halogens to form tetrahalides.

Because hafnium has a good absorption cross section for thermal neutrons, excellent mechanical properties, and corrosion resistance, it's used for reactor control rods. It's also used in gas-filled and incandescent lamps.
