Lanthanum Fluoride particles are white solid particles, the main components are lanthanum and fluorine, with good chemical stability, low water solubility, high melting point, and play an important role in the fields of optical materials, fluorescent materials, catalysts, and electronic materials.
Characteristics
Molecular weight: 195.90 g/mol
Density: 5.936 g/cm³.
Melting point: 1493°C
Boiling point: 2330°C
Appearance: Lanthanum Fluoride is usually white granules.
Solubility: almost insoluble in water, but soluble in alcohols and other organic solvents.
Hardness: Mohs hardness is between 4-5, with a certain degree of hardness.
Refractive index: The refractive index is high, about 1.6029, which makes it have some application value in the field of optics.
Stability: Lanthanum Fluoride has good chemical stability, but has a certain moisture absorption in the air, need to pay attention to moisture preservation.
Electrical Properties: Lanthanum fluoride is an ionic crystal with poor conductivity at room temperature, but at high temperatures or in a molten state, the mobility of ions increases and the conductivity is improved.
Optical properties: Lanthanum fluoride has good performance in optics. It has high refractive index and low light absorption coefficient, and has good transmittance in the visible and infrared light range, which can be used to manufacture optical glass, optical fibre, laser materials and infrared optical components.
Applications
Manufacture of optical glass: It can increase the refractive index of glass, improve the optical properties of glass, and be used to manufacture high-quality optical lenses, prisms and other optical devices.
Optical fibre: as the dopant of optical fibre, it can improve the transmission efficiency and stability of optical fibre, and has important applications in the field of optical fibre communication.
Laser materials: working substances used in the preparation of solid-state lasers, such as lanthanum fluoride crystals doped with rare earth elements can be used as laser gain medium to produce laser output.
Infrared optics: In infrared optical systems, lanthanum fluoride can be used to manufacture infrared windows, lenses and other optical components with good infrared transmission properties.
Electronics: It can be used to manufacture fluoride ion selective electrodes, which are used to detect the concentration of fluoride ions in solution in chemical analysis.
Metallurgical industry: used in the manufacture of special alloys, which can improve the performance of alloys, such as improving the hardness, strength and corrosion resistance of alloys; it can also be used in the electrolytic production of lanthanum metal.
Lighting source: used in the manufacture of carbon electrodes for arc lamps, which can improve the luminous efficiency and service life of arc lamps.
VI HALBLEITERMATERIAL GmbH (VIMATERIAL) employs a stringent quality assurance system to ensure the reliability of our product quality. Strict quality control is implemented throughout the entire production chain, and for defective products, we strictly enforce the principle of rework and redo. Each batch is released only after passing detailed specification tests.
Every batch of our materials is independently tested, and, if necessary, we send samples to certified companies for testing. We provide these documents and analysis certificates with the shipment to certify that our products meet the required standards.
