Fluoride is a compound of fluorine and magnesium, it looks no color and is a square block or powder, and the compound near the smell or taste. Although MgF2 looks very ordinary, but it is a kind of toxic chemical reagents, so in accordance with the conventional preservation methods is to separate on the glass bottle sealed preservation, and needs to be placed in the shade, no sunlight. At the same time storage of its glass bottles on the outer packaging needs to be marked in accordance with the requirements of toxic signs, to prevent the use of false information in the case of people and lead poisoning.

Just listen to the name of MgF2 we may feel strange, but I believe that as long as mention to familiar with a purpose which you will feel it. It is mainly used for optical lens coating, because after plating a layer of MgF2 film on the optical equipment we use, can effectively reduce the reflection lens interface for the incoming light, can greatly reduce the halo formation, so as to achieve the purpose of improving image quality.
In addition there are many other uses of magnesium fluoride, for example can be used in our life is closely related to the ceramic industry, electronic industry, because it can be used for the manufacture of porcelain or glass etc.. But also because of its toxicity, the operator must wear the correct protective equipment during the operation process, to deal with the accident after the accident. It also played a significant role in the industry, in the industry when smelting magnesium metal can be used as a flux, or in welding when some metal products can be used as a welding agent.
