Extended Data Figure 1: Equations of state of W.
From: The most incompressible metal osmium at static pressures above 750 gigapascals
a, Comparison of different EOSs of W reported in Dewaele et al.54, Sokolova et al.23, and Litasov et al.55, and this work. Although the curves agree for pressures up to about 50 GPa, there is a substantial discrepancy for pressures around 0.5 TPa. b, Pressure dependence of the unit cell volume of W. Experimental data points (red solid dots represent data collected using a Au–W mixture, green diamonds using a Pt–W mixture) were fitted using the third-order Birch–Murnaghan EOS (blue solid line, V0 = 31.674(3) Å3 per unit cell, K300 = 307(2) GPa, K′ = 4.53(4)); data are equally well fitted with the Vinet EOS (V0 = 31.686(7) Å3 per unit cell, K300 = 302(1) GPa, K′ = 4.82(3)).
