product key technologies
Production process characteristics
Vacuum melting and purification technology
Zirconium is chemically active and needs to be smelted under vacuum or inert gas protection.
Vacuum arc melting: Using high-purity sponge zirconium as raw material, the uniformity of the composition is controlled through multiple melting processes.
Electron beam melting/iodination method: used to prepare high-purity zirconium with a purity of over 99.95%, significantly reducing the content of oxygen and nitrogen impurities.
Plastic Processing and Organizational Control
Hot rolling/forging: Perform plastic deformation in the 500-600 ℃ range to optimize grain structure and enhance strength.
Heat treatment: Vacuum annealing eliminates stress, finely regulates grain size (usually ≤ 50 μ m), and ensures mechanical properties.
core features
Extreme environmental stability
Corrosion resistance: The surface self generated zirconia film (ZrO ₂) resists corrosion from hydrochloric acid, nitric acid, and seawater. The annual corrosion rate in a 300 ℃ seawater environment is only 1/100 of that of stainless steel.
High temperature performance: melting point 1852 ℃, significant high temperature strength, tensile strength still maintains 1400-1700MPa at 600 ℃.
Special nuclear properties
Ultra low heat neutron absorption cross section (0.18 target En) ensures the efficiency of neutron utilization in nuclear reactors.
application area
1. Nuclear energy field (core applications)
As a nuclear fuel cladding tube (such as Zr-4 alloy) and pressure vessel lining material, it can withstand high temperature and high pressure steam corrosion at 400 ℃. 90% of nuclear reactors worldwide rely on zirconium alloy to ensure safe operation. China's independent N36 zirconium alloy has been used in the "Hualong One" project, with a 20% improvement in radiation resistance.
2. Chemical and energy equipment
● Acid resistant reactor/heat exchanger: Annual corrosion rate<0.0025mm in 55% sulfuric acid (132 ℃) environment, with a lifespan of over 10 years.
● Key components of new energy: used for anti-corrosion coating of proton exchange membrane electrolysis cells, electrolyte deposition of solid-state batteries, and improving equipment stability.
3. Aerospace and Military Industry
● Rocket engine combustion chamber and aviation turbine blades: anti-oxidation at high temperature of 1200 ℃, Rolls Royce has achieved 100000 hours of fault free operation.
● Submarine pressure hull: resistant to deep-sea high pressure and seawater corrosion.
4. High end manufacturing and healthcare
● Semiconductor target material: ZrCl ₄ etching gas prepared from 99.999% high-purity zirconium for nanoscale etching of 12 inch wafers.
● Medical implants: Zirconia porcelain dental implants have a bone bonding speed 30% faster than titanium alloys, and have excellent long-term compatibility with artificial joints.
Zirconium board, as a key material in modern industry, plays an irreplaceable role in fields such as nuclear power, chemical industry, and medical industry due to its excellent corrosion resistance, nuclear performance, and biocompatibility. With the advancement of technology and industrial upgrading, the application prospects of zirconium plates will become even broader, continuously empowering human technological progress and sustainable development.
