Lithium Fluoride LiF is a white powdery crystal and is a toxic chemical. Although it cannot be in direct contact with it, it can be used in the welding of copper and aluminum after taking preventive measures.

Lithium Fluoride LiF is a white powdery crystal and is a toxic chemical. Although it cannot be in direct contact with it, it can be used in the welding of copper and aluminum after taking preventive measures. At the same time, it can also be used as a heat carrier for aerospace technology to store solar radiation heat energy, and it can also be used to make fluorinated glass. Or make prisms for spectrometers and X-ray monochromators, raw materials for lithium-ion batteries, etc.

It is not difficult to see from the above information that Lithium Fluoride LiF has many uses, not only as a desiccant and flux, but also as an insulating material.

Lithium Fluoride LiF

There are currently two production methods for Lithium Fluoride LiF:

There are two methods of neutralization and metathesis. Industrial production mostly adopts neutralization method.

The neutralization method is to prepare Lithium Fluoride LiF by reacting lithium carbonate or lithium hydroxide with hydrofluoric acid. That

Li2CO3+2HF=2LiF+CO2+H2O

Add solid lithium carbonate into the hydrogen fluoride solution to react to precipitate LiF crystals, filter and dry to obtain the product.

It should be noted that Lithium Fluoride LiF is a non-combustible substance, so it can be mixed with water and sand to be used as a fire extinguishing agent.
