| Abstract: | Synthesizing superhard material at high temperature and high pressure needs the sealing medium. Pyrophyllite is the most common seal, pressure transfer and heat preservation, insulation material in domestic at present. In the paper, the properties of pyrophyllite especially after high temperature and high pressure were measured by X-ray, Raman spectrum and electron microscope. As a result, the valuable information for the production was found. |
