Left: Single-crystal elastic moduli of yttria measured by Brillouin spectroscopy through longitudinal and shear velocity measurements. The measurements have close correspondence to fits from the calculated elastic constants (solid curves). (From ref. 1.)

Right: Temperature dependence of elastic moduli. Linear least squares regressions to the variation of bulk and shear moduli with temperature result in derivatives of dK/dT = -17± 2 MPa/°C and dGVRH/dT = -8±2 MPa/°C.
