Diamond high-pressure inclusion and preparation method thereof

Abstract

Provided are a diamond high-pressure inclusion and a preparation method thereof. The diamond high-pressure inclusion includes a diamond high-pressure chamber and a solid high-pressure material inside the diamond high-pressure chamber, the high-pressure material being a material under a pressure greater than one atmosphere, and the method includes the following steps: taking a solid target material and at least two layers of a film-shaped carbon material as main raw materials, and subjecting to a high-temperature and high-pressure treatment to obtain the diamond high-pressure inclusion, in which the target material is encapsulated between two adjacent layers of the film-shaped carbon material, and the high-temperature and high-pressure treatment causes the carbon material to transform into the diamond high-pressure chamber which encapsulates the high-pressure material.
