| Research Abstract |
Diamond/SiC composites were synthesized from diamond and Si powders using a hot isostatic pressing (HIP) technique. Cubes of the composites with 14 and 26mm edge length were thereby fabricated, and an application to the second stage anvils in a Kawai-type high-pressure apparatus was attempted. Because the diamond/SiC composites are transparent to X rays, the present anvils are applicable not only to energy dispersive diffraction experiments but also to angle dispersive diffraction experiments and radiographic studies that need a larger window for X-ray passes.
