What is an interesting fact about hafnium?
Hafnium is the 45th most abundant element on Earth, comprising about 3.3 parts per million (ppm) of the Earth’s crust by weight, according to Chemicool. Hafnium is quite resistant to corrosion because of the formation of an oxide film on exposed surfaces.
What are the properties of hafnium?
Physical properties Hafnium is a bright, silvery-gray metal that is very ductile. Ductile means capable of being drawn into thin wires. Its melting point is about 2,150°C (3,900°F) and its boiling point about 5,400°C (9,700°F). Its density is 13.1 grams per cubic centimeter.
What are three uses for hafnium?
Hafnium is a good absorber of neutrons and is used in the control rods of nuclear reactors. Hafnium is also used in vacuum tubes as a getter, a material that combines with and removes trace gases from vacuum tubes. Hafnium has been used as an alloying agent in iron, titanium, niobium and other metals.
