  • The 6H carborundum anvil is used in the Mao-Bell hydrothermal diamond anvil cell, and the Raman spectra of different positions of the surface of the anvil under different pressures were measured. The pressures were calculated by using the R1 line of the ruby which was positioned in the cell. Then we discuss on the feasibility of using the 969 cm-1 Raman peak of the carborundum anvil for pressure measurement in certain conditions and the advantages and disadvantages of doing so. After that, we found the following formula for calculating pressures under room temperature, which can be used if one does not change the measurement point of the carborundum anvil.
