Abstract: | Abstract Using solid argon as pressure medium, quasi-hydrostatic pressure was obtained at room temperature in the diamond cell up to 90 GPa. The mechanism of the disappearance of ruby R lines and the applicability of ruby pressure scale under quasi-hydrostatic pressure above 100 GPa was discussed. The deviation of every pressure measured at nine positions in the cell per mean pressure was less than 1.5% at pressure below 80 GPa. |
