| Abstract: | A potential new use of room temperature ionic liquid for a pressure transmitting medium is introduced in detail. A systematic study of the pressure-induced solidification of 1-butyl-3-methylimidazolium tetrafluoroborate ([C4MIM][BF4]) is presented in a diamond anvil cell at pressures up to 30 GPa by combining ruby fluorescence and synchrotron X-ray diffraction measurements. Its hydrostatic properties have been determined with hydrostatic limit up to about 6 GPa, and a slight pressure gradient was found up to 21 GPa. These results indicate that this kind of ionic liquid is a good hydrostatic pressure transmitting medium. |
