| Abstract: | On the basis of the expenience summed up by the predecessors, to improve the calculative formula of lattice energy by analysing the relations among electric potential of Crystal internal lattice point with Madelung constant, the valid nuclear electricity Z * - in cation and the negetive charge Z - in anion. The formula is : V 0=1389.75∑Z0.8061Z * +·nZ -r 0(1-0.342r 0)。｛n=0.25(Z +-1) 2+2｝. The present formula possesses the merits of easily obtaining parameter, extensive applicability and small calculation error rate. |
