摘要
The bonded type and the mechanism of the Fe<sub>2</sub>B’s structure have been a very interesting problem to scientific workers in various fields at home and abroad. It has evoked much controversy the same as FeB. A study of the Fe<sub>2</sub>B in the electron theory is given based on the study of FeB and the calculating result of Fe<sub>2</sub>B’s melting point has been provided in the electron theory on the basis of the valence elctron structure for Fe<sub>2</sub>B in this note.
