Born mayer方程
WebA equação de Born-Mayer permite calcular de forma teórica a energia reticular de um cristal iônico. Foi deduzida pelo físico alemão Max Born e pelo químico norte-americano Joseph Edward Mayer em 1932, como um aprimoramento da equação de Born-Landé deduzida pelo mesmo Max Born e por Alfred Landé em 1918.
