| Abstract: | With the single crystals of diamond without boron as starting materials and then by adding boron atoms to their surfaces, aggregate crystals of boron-coated diamond (ACBCD) have been synthesized under high prcssure. By the analytical methods of modified particle-tracking autoradiography and use ofan ion microprobe, the microstructurc of the boron-atom distribution in the, ACBCD has been directly observed to test and vcrfy the distribution model of boron atoms. The TG-TDA's of some ACBCD's have been made. The reasons why the oxidation resistance and the chemical inertia for the ACBCD are excellent are explained. |
