Applications

Optical material field:

Laser crystal production: It can be used as a raw material for the preparation of laser crystals and plays an important role in laser technology. Cadmium fluoride crystals doped with specific elements are able to produce laser light, which is used in laser equipment, such as laser cutting, laser ranging, and laser medicine.

Glass manufacturing: in the glass industry, cadmium fluoride can be used to improve the optical properties of glass, reduce the refractive index and dispersion of glass, make the glass more transparent and uniform, can be used to manufacture high-quality optical glass, special glass, etc., for example, applied to optical instruments, eyeglasses lenses, camera lenses and other products.

Phosphor production: It is one of the important constituents of phosphor, which enables the phosphor to emit light of specific colours under the excitation of ultraviolet rays or electron beams, and is widely used in fluorescent lamps, cathode ray tubes (CRTs), plasma display panels (PDPs), and other display devices to improve the display effect and brightness.

Nuclear industry field:

Neutron absorber in nuclear reactor: Cadmium fluoride has high absorption capacity for neutrons, and can be used as neutron absorber in nuclear reactor to control the rate of nuclear reaction and maintain the safe operation of nuclear reactor.

Nuclear material processing aids: In the processing and treatment of nuclear materials, cadmium fluoride can be used as an additive to help improve the performance of nuclear materials and processing technology.

Electronic materials field:

Manufacture of electronic components: It can be used to manufacture some special electronic components, such as semiconductor devices, thin film resistors and so on. In semiconductor devices, cadmium fluoride can be used as a dopant or insulating layer material, affecting the electrical properties of semiconductors; in thin film resistors, cadmium fluoride can improve the stability and precision of resistance.

Electronic packaging materials: due to its chemical stability and insulating properties, it can be used as an additive in electronic packaging materials to improve the performance and reliability of packaging materials.

Catalyst field: In organic synthesis and some chemical reactions, it can be used as a catalyst or a carrier of catalyst to promote the reaction and improve the efficiency and selectivity of the reaction. For example, in some organic synthesis reactions, cadmium fluoride can help activate the reactants, reduce the activation energy of the reaction, so that the reaction is easier to carry out.

Other applications:
Aluminium brazing agent: In the welding process of aluminium and aluminium alloy, cadmium fluoride can be used as a brazing agent to help remove the oxide film on the surface of aluminium and improve the quality and strength of welding.
