摘 要：By transition metals（Fe,Ni,Mn,Co） and their alloys as catalysts during the diamond synthesis,some transition phases will be formed,such as Fe3C type carbides and y solid solutions.Based on the empirical electron theory of the solid and molecules,the valence electron structures of different kinds of carbides and y solid solutions and the relative electron density differences of various diamond/carbide and y solid solution/carbide interfaces were calculated and analyzed in this paper.The electron structure conditions of the ideal catalyst were presented by analyzing the different catalytic effects of the catalysts,which provide a new theoretical path to the optimal design of the catalyst composition.
