WebMolten salt is salt which is solid at standard temperature and pressure but has become liquid due to elevated temperature. Regular table salt has a melting point of 801 °C (1474 °F) and a heat of fusion of 520 J/g.. A salt that is normally liquid even at standard temperature and pressure is usually called a room-temperature ionic liquid, and molten … Aluminium oxide (or Aluminium(III) ... (~33%), the density of the liquid close to its melting point is 2.93 g/cm 3. The structure of molten alumina is temperature dependent and the fraction of 5- and 6-fold aluminium increases during cooling (and supercooling), ...

Molten cryolite is used as a solvent for aluminium oxide (Al2O3) in the Hall–Héroult process, used in the refining of aluminium. It decreases the melting point of aluminium oxide from 2000 to 2500 °C to 900–1000 °C, and increases its conductivity thus making the extraction of aluminium more economical. Cryolite is used as an insecticide and a pesticide. It is also used to give fireworks a yellow color.
