Description: White powder, insoluble in water, soluble in acid. It is very easy to absorb moisture and can quickly absorb moisture and carbon dioxide in the air. It should be placed in a sealed container. Uses: Used to prepare scintillators required by modern medical image display technology and nuclear science, rare earth crystal laser materials, fluoride glass optical fibers and rare earth infrared glasses. In the lighting source Used in the manufacture of carbon electrodes for arc lamps. Used in chemical analysis to make fluoride ion selective electrodes. In the metallurgical industry, it is used to manufacture special alloys and electrolytically produce metal lanthanum. Used as a material for drawing lanthanum fluoride single crystals. | Description: white powder, insoluble in water, soluble in acid.
