| Why this differs from similar rows: V0 extrapolated to 0 GPa from Y. B. Wang et al. (1996) decompression data over a low-pressure range (4.1-0.6 GPa); text attributes the difference from this study's measured value to residual pressure (~1.2 GPa) in the recovered sample. | ||||||||||||||||||||||||||
