In this study, synthetic sapphire crystals were used as anvils, coupled with a metal gasket, in a Merrill-Bassett-type pressure cell (sapphire-anvil cell (SAC)). Quartz and ruby chips were compressed in the cell and used as pressure calibrators for the SAC. In the sample-anvil interface, the relationship of the frequency shifts of the R1, R2 and 417 cm(-1) peaks with pressure was studied. They were constructed as new pressure calibrators. To test the applicability of the newly calibrated SAC, the Raman spectra of dolomite and calcite were measured in situ at room temperature.
