Production process

01.

Raw material processing, precision machining, and post-processing

Purification process: The hafnium content of nuclear grade zirconium should be controlled to be less than 0.01%. High purity zirconium (≥ 99.95%) is purified by electron beam melting or iodination method to reduce oxygen and nitrogen impurities.
Powder preparation: the particle size of zirconia ceramic powder needs to be ≤ 1 μ m, and yttrium oxide (Y ₂ O ≮) stabilizer is added to prevent phase change cracking, and spray granulation improves liquidity.
Precision machining: diamond tool turning (speed 800rpm), surface roughness Ra ≤ 0.4 μ m; Laser assisted processing achieves sub micron precision.
Heat treatment: Vacuum annealing (650-800 ℃) eliminates stress and improves toughness.
Surface treatment: acid pickling and passivation (ASTM B614 standard) to enhance corrosion resistance; Medical implants require biological coating modification.

Molding technology

Metal zirconium forming:

Forging forming: Hot forging (900-1000 ℃) or cold forging, using multi-directional forging to refine grain size for nuclear grade zirconium forgings.

3D printing: Selective laser melting (SLM) is used to prepare complex structural components with a density greater than 99.5%.
Ceramic component molding:

Dry pressing molding: Simple shaped components, pressure range of 8-10 MPa.

Isostatic pressure forming: Complex structural components, pressure 100-200MPa, density up to 99.9% of theoretical value.
Injection molding: Micro shaped parts with an accuracy of ± 0.1%.

Application Fields

1. Nuclear energy and energy
  Nuclear reactors: fuel cladding tubes (Zircaloy-4 alloy), pressure tubes, accounting for 90% of global zirconium usage.
  New energy: High purity zirconium target 1520 for solid-state battery electrolyte (LLZO) deposition; SOFC fuel cell separator.

2. High end manufacturing

Zirconium processed parts combine the characteristics of extreme temperature resistance, biological adaptability, and nuclear grade purity. The core of its process lies in purity control and innovation in additive manufacturing. In the future, it will develop towards intelligent processing (such as online monitoring of thermal stress) and green cycle technology.

Just as the atomic number 40 of zirconium means "connecting the past and ushering in the future", this kind of material is transforming from the "corrosion resistant supporting role" of traditional industry to the "performance protagonist" of new energy, biomedicine and other fields, and its development will continue to rewrite the engineering paradigm of human response to extreme environments.
