说明：
In this paper two kinds of borides are doped into graphite.We synthesize diamond with the Boron-doped graphite. The up and down of the diamond that gr ...展开
ows between the graphite and the catalyst have the diffrerent shapes. We give the relations of the Boron content and the crystal shape, the strengh, the heat resistence. On the surface of the diamond, the Boron content is higher than inside. 收起
