The field of use of hafnium workpiece mainly includes the following aspects:
1. Nuclear industry:
• Nuclear reactor control rods: Hafnium has a large thermal neutron absorption cross section and is an ideal neutron absorber, so hafnium plates can be used to manufacture control rods for nuclear reactors, which can effectively control the rate of nuclear reactions and ensure the safe operation of nuclear reactors.
• Reactor structural materials: Its good plasticity, processing performance, high temperature resistance and corrosion resistance make it suitable for reactor structural materials, which can maintain stable performance in the complex environment of nuclear reactors.
2. Aerospace field:
• Engine components: Hafnium plates can be used to manufacture heat-resistant components of aircraft engines, such as turbine blades, combustion chambers, etc.In the high temperature, high pressure working environment, hafnium plate can maintain good mechanical properties and structural stability, helping to improve the performance and reliability of the engine.
• Rocket nozzle: rocket launch needs to withstand extremely high temperature and pressure, alloy materials containing hafnium have excellent high temperature resistance and thermal shock resistance, so hafnium plate is often used to manufacture rocket nozzle, to ensure the normal launch and operation of the rocket.
• Aircraft protective layer: some alloys containing hafnium can be used as protective layer materials for aircraft, such as the protective layer of spacecraft.These alloys have high creep strength, oxidation resistance and other characteristics, which can provide effective protection for spacecraft in the harsh space environment.
3. Electronics industry:
X-ray tube cathode: Hafnium easily emits electrons and can be used to manufacture cathodes for X-ray tubes, which have a wide range of applications in X-ray equipment in medical, industrial testing and other fields.
Electronic components: can be used to manufacture high-speed electronic tubes, microwave devices and other electronic components, using their special physical properties to meet the needs of electronic devices for high-performance materials.
• Semiconductor manufacturing: In the semiconductor manufacturing process, hafnium plates can be used to make components such as gate insulation for semiconductor chips.For example, hafnium dioxide has long been used as a gate insulator for microelectronics and integrated circuit dielectric devices, and its compatibility with integrated circuit processes is high, helping to improve the performance of semiconductor devices.
4. Chemical industry:
• Corrosion resistant parts: Hafnium plate has good corrosion resistance and can be used to manufacture corrosion resistant parts in chemical equipment, such as reactors, pipelines, valves, etc., and can maintain stable performance in some corrosive chemical production processes.
• Getter: Hafnium can be used as an getter for many inflation systems, which can remove unnecessary gases such as oxygen and nitrogen in the system to ensure the normal operation of the system and the quality of the product.
