Abstract:

Reiss and Pitzer's theory on the melt of simple organic salt has been analysed and complemented. Based on the dynamic and thermodynamic melting model of ionic salts, the factors which determine the melting points of simple ionic salts are proposed, they are the retiprocal of the sum of cationic radius and anionic radius ,the ratio of the radii of cation and anion and ionic non-spherical parameter. The melting points of alkali halide melts, alkali-earth halide melts and alkali salts including non-spherical anion have been investigated by artificial neural network, with good result.

Key words: Inorganic salt, Melting point, Artificial neural network method
