Method for preparing high-pressure state material capable of being detached from high-pressure device

Abstract

The present invention relates to the field of materials, in particular to a method for preparing a high-pressure state material that can be detached from a high-pressure device. The method comprising: placing a carbon material and a target material into a high-pressure device, and subjecting the resultant to high-temperature and high-pressure treatment to obtain a diamond high-pressure chamber containing a high-pressure state material inside. The present invention enables the high-pressure state material (including the substance and its pressure state) to be preserved inside the diamond high-pressure chamber by mixing the carbon material and the target material and placing into the sample chamber of a conventional high-pressure device, and then transforming the carbon material into diamond using the high-temperature and high-pressure treatment. The diamond high-pressure chamber can be separated from the conventional high-pressure device and maintain the high-pressure state inside, thus allowing the high-pressure material to be studied and applied in an atmospheric pressure environment.
