Atomic Number Of Hafnium
Hafnium is a chemical element discovered relatively recently and given the name after the Latin word for Copenhagen. It is a shiny metal of light grey color which is quite well resistive to corrosion. It is usually obtained from natural zirconium ores, and also it can be synthesized in the labs. This element has no biological importance. It is mainly used in nuclear reactors and for welding processes, and its alloys with such metals as titanium, iron, and others, are used as super strong steels in various production fields. In chemical industry, hafnium is sometimes used as an effective catalyst for various chemical processes.
