ZH-YF-M
Yttrium fluoride has the characteristics of low refractive index and high transmittance in the ultraviolet and infrared light regions. It can be used for optical coating. It can be plated on the surface of optical elements such as optical lenses and prisms to reduce reflection and increase transmittance.
As a doping matrix material, it is used to manufacture rare earth-doped laser crystals to achieve efficient laser emission and is used in laser processing, laser medical treatment, laser communication and other fields.
In the semiconductor plasma spraying process, yttrium fluoride powder is used as a coating material, mainly to improve the heat resistance, corrosion resistance and insulation properties of semiconductor manufacturing equipment.
Other applications: In addition, yttrium fluoride can be used to make high-efficiency phosphors for LED lighting and display backlighting; yttrium fluoride can also be used as a ceramic material to make high-performance ceramics and electronic ceramics. Our yttrium fluoride can also be used as a catalyst to increase the reaction rate; yttrium fluoride also plays a great role in the nuclear industry, electronic materials and scientific research.
Q: Can you provide yttrium fluoride samples?A: Yes, Free samples are available upon request. For customers with expected long-term business cooperation, we can cover the freight costs. However, sample provision may not be fulfilled under special circumstances such as strict regulatory policies, and we appreciate your understanding.
Q: What documents are required for export?A: Can in obtaining rare earth export licenses.
Q: How does the laser crystal work on the laser equipment?A: The laser crystal is usually placed inside the laser resonator as a gain medium. In the resonator, the laser crystal amplifies the light signal through stimulated emission to generate laser.
Q: What is the working principle of semiconductor plasma spraying?A: A surface treatment technology that uses high-temperature plasma to heat the spraying material (such as ceramics, metals or composite materials) to a molten or semi-molten state and spray it onto the substrate surface at high speed to form a high-performance coating.
