High-purity gadolinium oxide plays a key role in the nuclear industry due to its high thermal neutron absorption cross section. It is used to manufacture nuclear reactor control rods, which absorb thermal neutrons like a "speed governor", control the nuclear reaction rate, and ensure the safe and stable operation of nuclear reactors.
High-purity gadolinium oxide is used in a variety of magnetic materials. When high-purity gadolinium oxide interacts with metals such as iron and cobalt, it forms alloys or compounds with special magnetic properties. These products are widely used in the manufacture of computer hard disk heads, magnetic recording media, and magnetic sensors.
High-purity gadolinium oxide is widely used in the field of electronic ceramics. It can act as an additive or as a main component to optimize the dielectric and piezoelectric properties of ceramics and can be used in sensors.
Other applications: In the process of exploring and preparing high-temperature superconducting materials, a series of gadolinium-containing superconducting materials represented by gadolinium barium copper oxide (GdBCO) have emerged, and they have shown great application potential in cutting-edge fields such as superconducting cables and superconducting magnets. These gadolinium-containing superconducting materials can achieve resistance-free power transmission and realize zero-loss and efficient transmission of electricity. At the same time, they can be used to generate strong magnetic fields, providing support for equipment such as nuclear magnetic resonance imaging and particle accelerators that have strict requirements for strong magnetic field environments, and promoting the innovation and development of technologies in related fields.
Q: Can you provide high-purity gadolinium oxide samples?A: We can provide samples of about 10g-50g.
Q: How do you transport the goods?A: We have land, sea and air transportation, but we mainly use sea transportation.
Q: Is high-purity gadolinium oxide used in the medical field?A: Yes, it is used to prepare magnetic resonance imaging (MRI) contrast agents
Q: What role does high-purity gadolinium oxide play in the nuclear industry?A: In the nuclear industry, high-purity gadolinium oxide is often used as control rods and neutron absorbers in nuclear reactors because of its good absorption capacity for neutrons.
