Reiss and Pitzer’s theory on the melt of simple organic salt has been analysedand complemented. Based on the dynamic and thermodynamic melting model of ionicsalts, 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 theradii of catation and anion and ionic non-spherical parameter. The melting points of alkalihalide melts, alkali-earth halide melts and alkali salts including non-spherical anion havebeen investigated by artificial neural network, with good result.
