Introduction
Zirconium is a chemical element with the symbol Zr and atomic number 40. It is a lustrous, gray-white, strong transition metal that resembles hafnium and titanium. Zirconium is widely used in various industries due to its unique properties and applications. In this glossary, we will explore what zirconium is, its properties, uses, and significance in different fields.
What is Zirconium?
Zirconium is a highly corrosion-resistant metal that is commonly found in nature as the mineral zircon. It is extracted from zirconium silicate ore through a series of chemical processes. Zirconium is known for its high melting point, excellent thermal and electrical conductivity, and resistance to corrosion. It is used in various industries, including aerospace, nuclear power, and medical devices.
Properties of Zirconium
Zirconium has a melting point of 1855 degrees Celsius and a boiling point of 4371 degrees Celsius. It has a density of 6.52 grams per cubic centimeter and a Mohs hardness of 5. Zirconium is a ductile metal that can be easily shaped into different forms. It is non-magnetic and has good heat and electrical conductivity. Zirconium is also highly resistant to corrosion, making it suitable for use in harsh environments.
Uses of Zirconium
Zirconium is used in a wide range of applications due to its unique properties. In the aerospace industry, zirconium is used in the production of aircraft components, such as engine parts and structural materials. In the nuclear power industry, zirconium is used as a cladding material for fuel rods in nuclear reactors.
