METHOD FOR PREPARING HIGH-PRESSURE-STATE MATERIAL CAPABLE OF BEING SEPARATED FROM HIGH-PRESSURE APPARATUS

WIPO Patent Application WO/2023/216365

A1

The present invention relates to the field of materials, and specifically provides a method for preparing a high-pressure-state material capable of being separated from a high-pressure apparatus. The method comprises: putting a carbon material and a target material into a high-pressure apparatus, and performing high-temperature and high-pressure treatment to obtain a diamond high-pressure cabin that contains a high-pressure-state material therein. By mixing and putting the carbon material and the target material into a sample cavity of a traditional high-pressure apparatus, and then using high-temperature and high-pressure treatment to convert the carbon material into diamond, the high-pressure-state material (comprising a substance and a pressure state thereof) can be sealed in the diamond high-pressure cabin. The diamond high-pressure cabin can be separated from the traditional high-pressure apparatus and keeps an internal high-pressure state, so that the high-pressure-state material can be researched and used in a normal-pressure environment.
