AbstractThe elastic constants of ice VI have been determined at ?2 °C and 7.2 kbar by single crystal Brillouin spectroscopy. The adiabatic elastic moduli were found to be C11=26.8, C12=14.5, C13=12.8, C33=26.2, C44=6.3, and C66=10.4×104 bar, within approximately 1.5%. Large (125 mm3) single crystals were grown in a high pressure cell and in situ Brillouin spectra were collected at various crystal orientations about the laboratory z-axis. Ice VI crystals were oriented, while under pressure, by using the birefringent properties and Brillouin spectral behavior. Several polycrystalline elastic properties are derived using the bulk adiabatic moduli and a comparison with previous results is made.
