In order to solve the problems of high equipment investment, insufficient quantity , and limitedxperimental space in traditional high-pressure physics experiment teaching,the virtual simulation experimentf ultra-high pressure physics experiment technology was independently developed.The experiment is based onhe synthesis and analysis process of superhard material cubic boron nitride. It is divided into threeexperimental tasks; raw material weighing and pretreatment, high-temperature and high-pressure syntheticsample with six-sided top hydraulic press ,and sample performance test and analysis.The experimental operationallows students to independently set experimental parameters and synthesis conditions within a certain range,and through continuous simulation exercises , form a correct understanding of the experimental process , theoperation of instruments and equipment ,and an in-depth understanding of the principles of superhard materialsynthesis,so as to enhance students’ability to learn independently ,explore problems , and solve problems.
