NOVELTY - Preparing high pressure device separated high pressure state material comprises (i) adding the carbon material and the target material into a high pressure device and (ii) processing at high temperature and high pressure to obtain the diamond high pressure cabin containing high pressure material inside. USE - The method is useful for preparing high pressure device separated high pressure state material. ADVANTAGE - The method can separate diamond high pressure cabin from the traditional high-pressure device and maintain a high-pressure state inside, so that high-pressure materials can be studied and applied in a normal pressure environment.
