Abstract: An influence of bond structure factors containing ionic charge, coordination radius and electron configuration etc. on the thermodynamic property of carbonates is investigated by means of the bond parameter function CASP scale.Anew method for predicting the standard formation free energy of the carbonates is established, and the△Gf0 values of some carbonates are calculated, the results are in good agreement with the relative values from literatures. There are some△Gf0 values of the carbonates in literatures, which seem to be unusual and are also discussed in this paper.

Key words: Thermodynamic property, Standard formation free energy, Carbonate
