What Is The Melting Point Of Aluminium Fluoride?

The melting point of aluminium fluoride (AlF3) is approximately 1,292 degrees Celsius (2,358 degrees Fahrenheit). This means that at this temperature, solid AlF3 will transition into a liquid state.

Aluminium fluoride is an inorganic compound that occurs naturally as the mineral rosenbergite. It is commonly used as a flux in the production of aluminium metal and various other applications, including ceramics, glass, and electronics.

The melting point of AlF3 is relatively high compared to other common substances, such as water or table salt, which have melting points of 0 degrees Celsius and 801 degrees Celsius, respectively. This high melting point is due to the strong ionic bonds between the aluminium and fluoride ions in the crystal lattice structure of the solid material.

It's worth noting that the exact melting point of AlF3 can vary slightly depending on factors such as impurities in the material, pressure, and heating rate. Therefore, the reported melting point range for AlF3 may be between 1,270 and 1,300 degrees Celsius.
