Zirconium has a wide range of applications. It is mainly used in the fields of ceramics, refractory materials, etc. in the form of zirconium silicate and zirconium oxide. Only 3%-4% of zirconium ore is processed into metallic zirconium (or sponge zirconium), and then further processed into various zirconium materials. Because metallic zirconium has the characteristic of a small thermal neutron absorption cross-section, metallic zirconium has excellent nuclear properties. Nuclear-grade zirconium uses this property to be used as a structural material for nuclear-powered aircraft carriers, nuclear submarines, and civilian power reactors, and as a cladding for uranium fuel elements. Nuclear-grade zirconium can be regarded as an important strategic metal for the country and is closely related to the development of the nuclear industry. As an active metal, zirconium will form an oxide film at room temperature. This oxide film gives zirconium and its alloys excellent corrosion resistance. At the same time, zirconium has good mechanical and heat transfer properties
