Shape: coiled wire, granule, natural coil. Hafnium metal has excellent welding performance, processing performance, high temperature resistance and corrosion resistance, so it has become an important material in the atomic energy industry. Hafnium has a large thermal neutron capture cross section and is an ideal neutron absorber, which can be used as control rods and protection devices in atomic reactors.

1. Purity requirements:
• High purity is the key, and the purity of hafnium wire is generally required to be 99.9% and above.High purity hafnium wire can ensure the stability and consistency of the material in the evaporation process, reduce the influence of impurities on the quality of the evaporation coating, so that the film produced by evaporation has good performance and purity.
2. Dimensional accuracy requirements:
Diameter accuracy: The diameter of hafnium wire needs to maintain a high degree of consistency, and usually the diameter error should be controlled within a very small range.For example, for some high-precision evaporation applications, the diameter error of the hafnium wire may need to be controlled within ±0.05mm, so as to ensure the stability of the evaporation rate and evaporation amount of the material during the evaporation process, thus ensuring the uniformity of the film.
• Length requirements: According to different evaporation equipment and process requirements, the length of hafnium wire also needs to be accurately controlled.Too long or too short hafnium silk may affect the normal operation of the equipment and evaporation effect.
3. Surface quality requirements:
• Finish: Hafnium wire surface should have a high finish, no obvious scratches, pits, burrs and other defects.The smooth surface can ensure the uniform evaporation of the material during the evaporation process and avoid the local evaporation rate difference caused by the uneven surface, thus improving the quality of the evaporation coating.
• Cleanliness: The surface should be kept clean, free of oil, dust, oxides and other impurities.These impurities may be mixed into the evaporation coating during the evaporation process, affecting the purity and performance of the film.
4. Mechanical performance requirements:
• Strength: Hafnium wire needs to be strong enough to withstand mechanical stresses generated during installation and use to avoid breakage or deformation.For example, when the hafnium wire is installed on the evaporation source of the evaporation equipment, the hafnium wire needs to be fixed and stretched, which requires that the hafnium wire has a certain strength to withstand the stress during these operations.
• Toughness: Good toughness can make hafnium wire is not easy to break when subjected to external forces, especially in some complex evaporation processes, it may be necessary to bend or fold the hafnium wire, which requires that the hafnium wire has a certain toughness to adapt to these operations.
5. Evaporation characteristics:
• Evaporation rate: Hafnium wire needs to have a suitable evaporation rate, neither too fast nor too slow.Too fast evaporation rate may lead to too fast growth rate of the film, which will affect the structure and properties of the film.If the evaporation rate is too slow, it will reduce the production efficiency and increase the production cost.
• Evaporation stability: During the evaporation process, the evaporation rate and evaporation amount of hafnium wire need to be maintained to ensure the uniformity and consistency of the evaporation coating.This requires that the material composition, structure and manufacturing process of hafnium wire should have good stability.
6. Chemical stability requirements: In the evaporation process, hafnium wire needs to be in contact with other materials and gases, so it needs to have good chemical stability to avoid chemical reactions or interactions with other materials, thereby affecting the quality and performance of the evaporation coating.
