Saturation curve of SiO2 component in rutile-type GeO2: A recoverable high-temperature pressure standard from 3 GPa to 10 GPa

Ge0.57Ti0.43O2: a new high-pressure material with rutile-type crystal structure

“…Thus, the pressure standard and the GeO 2 -TiO 2 glass were treated at the same conditions. The details on the pressure calibration technique can be found elsewhere (Gullikson et al, 2015;Leinenweber et al, 2015). The applied temperature was sufficient to produce high-quality single crystals with uniform extinction in the optical microscope.…”
