Diamond Anvil

Brillouin scattering spectra and their transverse mode were measured for paraffinic and naphthenic synthetic lubricants, employing a high-pressure diamond anvil cell (DAC). Sound velocity, density, refractive index, and shear modulus under high pressure were obtained. The density obtained from the thermodynamic relation was compared with that from Lorentz-Lorenz‘s formula. The densities were also compared with Dowson‘s density-pressure equation of lubricants. The sound velocity in the transverse mode and shear modulus were obtained for 5P4E up to 2.7 GPa. A slope change in the pressure-sound velocity diagram was confirmed at about 0.3 GPa, which may be associated with crystallizaton of 5P4E, observed through a diamond optical window in the DAC.
