Industrial pure zirconium target, zirconium tube
Zirconium is used in nuclear reactors mainly because of its excellent corrosion resistance and high temperature resistance. Some specific uses of zirconium in nuclear reactors include:
1. Cladding material: Zirconium alloy, such as zirconium alloy, is used to make the cladding around the nuclear fuel pellets in the fuel rods of nuclear reactors. The zirconium cladding provides a barrier containing radioactive fuel and prevents the release of radioactive material into the reactor coolant.
2. Structural parts: Zirconium alloy is used for various structural parts in the reactor core, such as support structures and other key components that require high-temperature strength and corrosion resistance.
3. Control rods: Control rods are made of zirconium-based alloy and regulate nuclear reactions by absorbing neutrons and controlling the fission rate in the reactor core.
Overall, zirconium’s corrosion resistance, high-temperature stability, and low neutron absorption make it an important material for the safe and efficient operation of nuclear reactors. Its use in nuclear applications helps ensure the integrity and safety of reactor cores and associated components.
Zirconia and zirconium are related materials, but they have different properties and applications.
Zirconium is a chemical element with the symbol Zr and atomic number 40. It is a lustrous gray-white metal that is highly resistant to corrosion. Zirconium is commonly used in a variety of industrial applications, including nuclear reactors, chemical processing equipment, and aerospace components.
Zirconia, on the other hand, is a compound derived from zirconium. Specifically, zirconia is the oxide of zirconium, with the chemical formula ZrO2. Zirconia is a ceramic material with high strength, high hardness, wear resistance and corrosion resistance. Its applications include dental ceramics, refractories, thermal barrier coatings, and structural ceramics in various industries.
In summary, zirconium is a metallic element and zirconium oxide is an oxide derived from zirconium. Zirconium is used in metal applications, while zirconia is used as a high-performance ceramic material in various industrial and technical fields.
The density of zirconium at room temperature is approximately 6.52 grams per cubic centimeter (g/cm3). Zirconium is a lustrous, gray-white metal with a relatively high density that is suitable for a variety of industrial applications, including nuclear reactors, chemical processing equipment and aerospace components.
