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 CASPscale. A new method for predicting the standard formation enthalpy ΔH0f of the carbonates is established,and the values of some carbonates are calculated,the results are in good agreement with the relative values from literatures.There are some H0f values of the carbonates such as MgCO3,Tb2(CO3)3 etc.in literatures,which seem to be unusual and are also discussed in this paper.

Key words: Thermodynamic property, Standard formation enthalpy, Carbonate
