Lanthanum (III) fluoride, with the chemical formula LaF3, is an inorganic rare earth compound. It appears as a white powder with a vapor pressure of 922 mmHg at 25 °C. This compound has 3 hydrogen bond acceptors and a small topological molecular polar surface area, which contributes to its unique chemical and physical properties. Lanthanum fluoride is almost insoluble in water but soluble in alcohol solvents, making it suitable for various industrial processing methods.
Our lanthanum fluoride powder is available in purity levels ranging from 99% to 99.99% (calculated as La2O3/REO), allowing commercial users to select the appropriate grade based on their specific application requirements. The 99.9% purity grade is particularly widely used in optical scintillator manufacturing due to its balanced performance and cost characteristics.

Lanthanum fluoride exhibits several properties that make it valuable across multiple industrial sectors. Its low solubility in water provides excellent chemical stability in aqueous environments, while its solubility in alcohol solvents facilitates various processing techniques such as solution casting and powder mixing.
The compound's optical properties are particularly notable. When doped with cerium, lanthanum fluoride forms a scintillator material with an emission peak at 311 nm and a decay time of 26.5 μs. These specific optical characteristics make it suitable for use in radiation detection applications. It is important to note that cerium-doped LaF3 scintillators require pairing with quartz or UL% glass windows for optimal performance.
Lanthanum fluoride is a key raw material in the production of various optical components. Its primary optical application is in the preparation of scintillators used in medical imaging equipment. Additionally, it is used in the manufacturing of rare earth laser crystals, fluoride glass fibers, and infrared glass. These components find use in telecommunications, defense systems, and scientific research instruments.
In the industrial sector, lanthanum fluoride is used in the production of arc lamp carbon electrodes, which are essential for high-intensity lighting applications. It also serves as a critical material in the fabrication of fluoride ion selective electrodes, used for analytical measurements in chemical and environmental monitoring.
The metallurgical industry utilizes lanthanum fluoride in the production of special alloys and as an electrolyte for the electrolytic production of metal lanthanum. These alloys exhibit improved mechanical and corrosion-resistant properties compared to conventional materials.
Lanthanum fluoride plays a role in nuclear fuel reprocessing through the co-precipitation separation technology, specifically the lanthanum fluoride precipitation carrier method. This application leverages the compound's low solubility and ability to form stable precipitates with certain radioactive elements.
We offer lanthanum fluoride powder in purity levels from 99% to 99.99% (La2O3/REO). The 99.9% grade is the most commonly used for optical scintillator applications, while higher purity grades are available for specialized requirements.
No, lanthanum fluoride is almost insoluble in water. It is, however, soluble in alcohol solvents, which allows for various processing methods in industrial manufacturing.
Lanthanum fluoride powder should be stored in a cool, dry place in a tightly sealed container. It is chemically stable under normal storage conditions but should be kept away from strong acids and bases.
Pure lanthanum fluoride is not an efficient scintillator. It requires doping with cerium to exhibit the desired scintillation properties, including the characteristic 311 nm emission peak and 26.5 μs decay time.
Our lanthanum fluoride powder is produced under strict quality control conditions to ensure consistent performance across batches.
