Lanthanum fluoride is mainly used in the preparation of scintillators, rare earth crystal laser materials, fluoride glass optical fiber and rare earth infrared glass required by modern medical image display technology and nuclear science. It is used to make carbon electrode of arc lamp in lighting source. It is used in chemical analysis to make fluoride ion selective electrodes. It is used in the metallurgical industry to make special alloys and electrolysis to produce lanthanum metal. Used as a material for drawing lanthanum fluoride single crystal.
WONAIXI company has been producing rare earth fluoride for more than ten years. We have continuously optimized the production process, so that our rare earth fluoride products are of good quality, with high fluoridation rate, low free fluorine content and no organic impurities such as antifoaming agent. Currently, WNX has an annual production capacity of 1,500 tons of lanthanum fluoride. Our lanthanum fluoride products are sold at home and abroad for the preparation of lanthanum metal, polishing powder and glass fiber.
