Cadmium Fluoride[edit]

3D model of the fluorite unit cell, similar to the structure of cadmium fluoride.

Cadmium fluoride (CdF_) is an inorganic compound composed of cadmium and fluorine. It is a white crystalline solid that is highly soluble in water and has a fluorite crystal structure. Cadmium fluoride is used in various applications, including optics and electronics.

Structure[edit]

Cadmium fluoride crystallizes in the fluorite structure, which is a type of cubic crystal system. In this structure, each cadmium ion is surrounded by eight fluoride ions, and each fluoride ion is coordinated to four cadmium ions. This arrangement is similar to that of calcium fluoride (CaF_), which is the mineral fluorite.

Properties[edit]

Cadmium fluoride is a white, water-soluble solid. It has a melting point of approximately 1,110 °C and a boiling point of 1,749 °C. The compound is known for its high ionic conductivity and is used in various optical applications due to its transparency to infrared light.

Applications[edit]

Cadmium fluoride is used in the manufacturing of optical materials, such as lenses and windows, that require transparency to infrared light. It is also used in the production of certain types of lasers and in the electronics industry for the fabrication of thin films.

Safety[edit]

Cadmium fluoride is toxic and poses health risks if inhaled or ingested. It can cause damage to the lungs and kidneys and is considered a carcinogen. Proper safety precautions, including the use of personal protective equipment, are necessary when handling this compound.

+'''Cadmium fluoride''' (CdF_) is an inorganic compound composed of cadmium and fluorine. It is a white crystalline solid that is highly soluble in water and has a fluorite crystal structure. Cadmium fluoride is used in various applications, including optics and electronics.
-Cadmium fluoride is typically produced by the reaction of cadmium oxide (CdO) or cadmium carbonate (CdCO3) with hydrofluoric acid (HF):
-:CdO + 2HF → CdF2 + H2O
-:CdCO3 + 2HF → CdF2 + CO2 + H2O
-This process yields cadmium fluoride as a white powder, which can then be purified and processed into the desired form for various applications.
