The Kapustinskii equation calculates the lattice energy ''UL'' for an ionic crystal, which is experimentally difficult to determine. It is named after Anatoli Fedorovich Kapustinskii who published the formula in 1956. : : The calculated lattice energy gives a good estimation; the real value differs in most cases by less than 5%. Furthermore, one is able to determine the ionic radii (or more properly, the thermochemical radius) using the Kapustinskii equation when the lattice energy is known. This is useful for rather complex ions like sulfate (SO) or phosphate (PO). ==See also== * Born-Landé equation * Born-Haber cycle * Madelung constant 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Kapustinskii equation」の詳細全文を読む スポンサード リンク
