Zirconium is widely used in the fields of ceramics, refractories and the like in the form of zirconium silicate and zirconia. Only 3%-4% of the zirconium ore is processed into metal zirconium (or sponge zirconium) and further processed into various zirconium materials. Because metal zirconium has a small thermal neutron absorption cross section, metal zirconium has excellent nuclear properties. Nuclear grade zirconium is used as a structural material for nuclear power aircraft carriers, nuclear submarines and civil power reactors, and uranium fuel components. Enclosures, etc. Nuclear grade zirconium can be regarded as an important strategic metal of the country and closely related to the development of the nuclear industry.
As an active metal, zirconium forms an oxide film at room temperature, which makes zirconium and its alloys have excellent corrosion resistance. At the same time, zirconium has good mechanical and heat transfer properties, coupled with significant cost advantages, making it an excellent corrosion-resistant structural material in the petrochemical industry today.
Zirconium used in chemical acid and alkali resistant equipment, military industry, and electronics industry is called industrial grade zirconium. From the aspects of processing difficulty, process level and technological content, metal zirconium and its alloy products are at the top of the industrial chain.
