The diamond powders synthesized in different growth systems were studied. The shape and size of diamond powder grains were determined by means of a scanning electron microscope. The epithermal neutron activation analysis allowed us to determine the element content of impurities. The results showed that in the Fe–Ni–C system the grains in the diamond powder are larger with the right shape and high strength characteristics than those in the Mn–Ni–C system. The grains of the Fe–Ni–C system are also characterized by minimal impurities that explain the lower rate of crystal growth.
