Introduction Of Zr Plate
A zirconium plate is an alloy plate made from a mixture of titanium, zirconium, and aluminum. It has excellent mechanical properties, high corrosion resistance, strong heat absorption, and good thermal aging performance. The surface of the zirconium plate is soft and easy to repair, easy to scratch, strong impact resistance in the production of precision instruments, complex electronic components, and other precision products of the ideal material.

The main characteristics of zirconium plates are as follows:
1. High temperature stability: Zirconium plates can maintain stable physical and chemical properties at high temperatures, which makes them widely used in nuclear industry, aerospace and other fields.
2. Corrosion resistance: Zirconium plates have good corrosion resistance to most acids, alkalis, salts and other chemical substances, and can maintain this property even in high temperature and high pressure environments.
3. Low thermal neutron absorption cross-section: This is an important reason why zirconium plates are widely used in the nuclear industry. Its thermal neutron absorption cross-section is only 1.8 nm, which is much lower than other common structural materials, which means that its thermal neutron absorption ability is extremely weak and is very suitable for use as a structural material for nuclear reactors.
4. Good mechanical properties: Zirconium plate has high strength, excellent plasticity and toughness, which allows it to maintain good performance under harsh conditions such as impact and vibration.
Main applications of zirconium plates.
Due to its excellent properties, zirconium plates are widely used in the following fields:
1. Nuclear industry: As mentioned above, zirconium plates are widely used in the construction of nuclear reactors, including fuel cladding, control rods, pressure vessels, etc., due to their low thermal neutron absorption cross-section characteristics.
2. Chemical industry: Due to its excellent corrosion resistance, zirconium plates are used to manufacture various chemical reactors, heat exchangers, and pipelines.
3. Aerospace: In extreme high-temperature and high-pressure environments, the stability and good mechanical properties of zirconium plates make it an ideal material for manufacturing aircraft and rocket parts.
4. Medical devices: Due to its good biocompatibility, zirconium plates are also used to manufacture artificial bones and other medical devices.
In general, zirconium plate, as a new material with many excellent properties, is playing an important role in various fields.
