Zirconium Rod Description
Zirconium (Zr) is a silver metal with a density of 6.52 g/cm3. Zr has a very small neutron adsorption cross-section and relatively high melting point (1855℃ or 3371℉), making zirconium a great material for nuclear power rods. In the 1990s, about 90% of zirconium produced every year is consumed by nuclear industry. However, as more and more people get familiar with Zr and its compound, more applications has been found. Zirconium metal and zirconium alloys has advantages in specialized chemical environments - primarily acetic and hydrochloric acids. The corrosion resistance of zirconium comes from a tightly adhered oxide that forms almost instantaneously. As a result, zirconium has been used to make electrodes components, foils, flanges bolts, tubes and rods for special applications. Zirconium products also have wide applications in medical equipment, such as zirconium implants.
A zirconium (Zr) rod is ideal for use in a nuclear power rod because of its small neutron absorption cross-section and a high melting point of 1855℃ (3371℉). This silvery metallic element also leads to better wear resistance and hardness of commercial amorphous metals, more commonly known as metallic glass.
Zirconium is ductile and easily workable. However, proper lubricant must be used to prevent galling.
