Abstract
It has been reinforced by Kushwah et al. (Kushwah, 2013) that the Lindemann law doesn’t work satisfactorily for the transition metals. We think this point is open to question. Combining the Lindemann law and the Vinet et al thermal equation of state with the melting curves of bcc Mo, we present an explicitly simple expression of the pressure dependency Grüneisen parameter g for Molybdenum. The results yield good agreement with density functional theory and experiments.
Highlights
The transition metal Molybdenum (Mo) has wide engineering and technology application for its thermal and mechanical strength and chemical resistance (Errandonea, 2001; Santamaría-Pérez, 2009; Belonoshko, 2008; Moruzzi, 1988)

Considerable experimental and theoretical methods had been developed for Mo to study its thermodynamic properties such as melting temperature Tm, thermal equation of state (EOS), Grüneisen parameter γ and Debye temperature ΘD, et al (Hixson, 1992; Zhang, 2008; Errandonea, 2005; Burakovsky, 2004; Kushwah, 2013; Zeng, 2011; Litasov, 2013; Al’tshuler, 1987; Asimow, 2009; Cazorla, 2007; Vinet, 1989)
