摘要：

We have studied high- pressure, high- temperature processing ( 7.0 GPa, 2000 - 2100 degrees C) of low- nitrogen boron- doped synthetic diamonds grown in the Fe - Ni - C system ( 5.5 - 6.0 GPa, 1350 - 1450 degrees C) with boron and titanium additions. The results indicate that, during the growth of low- nitrogen boron- doped diamonds, there is a competition between different acceptors ( boron and nickel). The system of point defects and their distribution over the crystal are not influenced by the processing; the uniformity of coloration in natural diamonds is governed by the prevalence of octahedron growth sectors.
