Production process characteristics
Vacuum melting and precision casting
Zirconium is chemically active and needs to be melted under vacuum or inert gas (argon) protection:
Vacuum arc melting: using high-purity sponge zirconium as raw material, optimizing composition uniformity through multiple melting processes;
Electron beam cold bed melting: used for nuclear grade zirconium rods, with impurity content reduced to ppm level and grain size ≤ 50 μ m.
Key technologies of plastic processing
Extrusion forming: special glass powder+molybdenum disulfide lubricant to prevent mold sticking and solve the problem of poor fluidity of zirconium alloy;
Multi directional forging: Crush the as cast microstructure at 800-950 ℃, refine grain size (≤ 100 μ m), and improve mechanical properties.
Precision heat treatment control
Precision annealing (500 ℃ as the gold point) is key - complete recrystallization structure and 10-150nm dispersed second phase synergistically enhance corrosion resistance; Temperatures above 600 ℃ can cause coarsening of precipitates and a threefold increase in corrosion rate.
application area
1. Nuclear energy industry
● Fuel cladding tube: Zirconium alloy rods (such as Zr-4, R60702) wrap around nuclear fuel, utilizing their low thermal neutron absorption cross section (0.18 target En) to ensure neutron transfer efficiency and prevent radioactive leakage.
● Control rod structural components: regulate the nuclear reaction rate and maintain structural stability in high temperature and high pressure environments.
● Nuclear waste storage container: Its radiation corrosion resistance ensures long-term sealing safety.
2, High end chemical equipment
● Acid resistant reactor components: The annual corrosion rate is less than 0.002mm in boiling concentrated nitric acid (220 ℃), and the service life is more than three times that of stainless steel. They are used for stirring shafts, valves, etc.
● Electrolytic cell electrode: resistant to corrosion by hydrochloric acid and sulfuric acid in the chlor alkali industry.
3, Biomedical
● Orthopedic implants: Zirconium rods are made into bone nails and joint prostheses through biocompatibility treatment, and the surface oxide film is non-toxic and wear-resistant.
● Dental implants: High purity zirconium rods (such as R60702) support root restoration, with a bone bonding speed 30% faster than titanium alloys.
4, Aerospace and Military Industry
● Aircraft engine components: turbine blades and combustion chamber liners resist oxidation at a high temperature of 1200 ℃, resulting in a 10% increase in thrust to weight ratio.
● Armor reinforcement material: Adding 0.1% zirconium to enhance the hardness and impact resistance of armor steel.
5, Special Industry and Scientific Research
● High temperature experimental furnace components: thermocouple protection tube, support rod (temperature resistance ≥ 1800 ℃).
● Semiconductor etching gas raw material: high-purity zirconium (99.999%) is used to prepare zirconium tetrachloride (ZrCl ₄) for nanoscale etching of wafers.
Zirconium rods, as a key material in modern industry, play an irreplaceable role in fields such as nuclear power, chemical engineering, and healthcare due to their excellent nuclear performance, corrosion resistance, and biocompatibility. With the advancement of technology and industrial upgrading, the application prospects of zirconium rods will become even broader, continuously empowering human technological progress and sustainable development.
