摘要
本文以 Born-Harb 循环为依据,推导了复合晶体晶格能和与其相应的各二元化合物晶体晶格能之间的关系,并由此给出了复合氧化物晶体晶格能近似计算的新公式。对20种复合氧化物晶体晶格能计算结果的分析表明:用本文所给公式对复合氧化物晶体晶格能进行近似计算是可行的。
On the basis of Born-Harb cycle,the relationship between lattice energy of complex ox- ides and that of the corresponding binary oxides has been established.A new formula for calculat- ing lattice energy of complex oxides has been given.Lattice energy of 20 complex oxides has been calculated by the new formula,and the agreenent between calculated values and experimental val- ues is satisfactory.
