Function:
1. It can significantly reduce the melting point of aluminum electrolyte, improve electrolytic efficiency, and reduce energy consumption.
2. In lithium-ion batteries, lithium fluoride can play a role in stabilizing the electrolyte and ensuring the normal operation of the battery.
3. The transmittance of ultraviolet light is high, so it can be used as a transparent window of ultraviolet light in optical materials.
4. It can be used as catalyst in organic synthesis reaction.
Application:
1. It is an important raw material for the manufacture of lithium-ion batteries, which can be used as solid electrolyte or coating material.
2. As an additive to improve electrical efficiency, it can reduce the melting point and viscosity of the electrolyte, improve the conductivity and current efficiency, thereby speeding up the production speed and reducing the cost of aluminum.
3. In the ceramic industry, it is used to reduce the kiln temperature and improve the heat shock resistance, wear resistance and acid corrosion of the material.
4. Used as a transparent window for ultraviolet rays, it can be used to manufacture fluorinated glass and refractive elements of X-ray monochromator.
5. In the field of nuclear energy and aerospace, lithium fluoride is used as a material for the manufacture of reactor fuel and turbine blades for turbine engines, as a neutron shielding material, and as a solvent in molten salt reactors.
6. In wavelength analytical X-ray fluorescence spectrometer, lithium fluoride can be used as a fluorophobe for fluorescence spectrum analysis, and can also be used as a flow agent in sample preparation to improve the stability and uniformity of the sample.
