Used in the production of fluorinated compounds and as a catalyst in fluorination reactions during organic synthesis. Employed in the manufacturing of specialty glasses and ceramics due to its ability to modify refractive index and thermal expansion properties. Applied in surface treatment processes to enhance corrosion resistance of metal components, particularly in humid and harsh chemical environments. Utilized in the semiconductor industry for doping silicon to improve electrical conductivity properties of semiconductor materials. Also used in research for developing new fluoride-based materials, such as the synthesis of special fluoride compounds or materials for optical devices. Additionally, employed in the production of fluorine gas and in the metal industry to control oxidation during alloy melting.
