Abstract
Provided are a pressure medium oil, containing a Group-14 element-containing organic compound selected from an organic germanium compound, an organic tin compound, and an organic lead compound, and a method for using a pressure medium oil, which includes applying a pressure to a substance via the pressure medium oil. The pressure medium oil does not solidify even under an ultrahigh pressure of more than 3.7 GPa at room temperature (25° C.) and has a low pour point, and hardly dissolves a conductive paste.
