Abstract

We have constructed semi-empirical equations of state of Al, Au, Cu, Pt, Ta, and W, which agree within experimental error bars with the shock wave, ultrasonic, X-ray, and thermochemical data in a temperature range from 10-20 K to melting temperature and to comprebion x=V/V0=0.5-0.6. The comparison of the calculated room isotherms for these metals with quasi-hydrostatic measurements of Dewaele et al. (2004a, b) supports recently proposed ruby prebure scales (Holzapfel, 2003; Dorogokupets and Oganov, 2003; Dewaele et al., 2004b). We recommend a new ruby prebure scale in the form P=A(δλ/ λ)×(1+B/2δ λ/ λ0) with parameters A=1884 GPa and B=11. The crob analysis on independent data of Akahama et al. (2002; 2004), Sata et al. (2002), Matsui and Nishiyama (2003), Nishiyama et al. (2004), Fei et al. (2004a, b) confirms the resulting equations of state of Al, Au, Cu, Pt, Ta, W, Ag, MgO, and diamond, whose room-Temperature isotherms can be used as an alternative for the ruby prebure scale.
