B, B+N, Y, Ce and rare-earth mixture (0.1—0.2%)were added respectively to the catalytic alloys Ni_(40) Mn_(30) Fe_(30). Experimental results indicate that the oxidation resistance of the diamonds increased greatly, and the mean compressive strength slightly, by the catalytic alloy containing boron (or boron and nitrogen). This catalyst may be widely applied to the synthesis of dark diamonds containing boron. As for rare-earth elements, there are some influences too.Samples of catalytic alloys containing and non-containing small amount elements were assembled half and half symmetrically in a reaction vessel to set up the horizontal concentration gradient of small-amount doping atoms. The influences of small-amount elements such as boron upon the synthesis of diamonds under high-pressure and high-temperature were investigated, thus obtaining some useful results.
