Zirconium is a metallic element with the atomic number 40 and the symbol Zr. It is a lustrous, grayish-white metal that is highly resistant to corrosion and has a high melting point. Zirconium is commonly used in nuclear reactors as a cladding material for fuel rods due to its excellent corrosion resistance and low neutron absorption cross-section. It is also used in various industries including aerospace, automotive, and medical devices. Research in zirconium focuses on its properties, applications, and potential advancements in materials science and engineering. Studies may include alloy development, surface modification, and characterization techniques to further enhance the performance and functionality of zirconium-based materials.
