摘要：The present study deals with the elastic behaviour of diborides (BeB2, MgB2 and NbB2) under high pressure with the help of equation of state (EOS) using the elastic data reported by Islam et al. It is concluded that EOS, which are based either on quantum statistical model orÂ pseduopotential model, only are capable of explaining high pressure behaviour of the solids under study. Â Moreover the value of first order pressure derivative of bulk modulus at infinite pressure (Kinfinity) is greater than 5/3 and thus the diborides under study do not behave as Thomas-Fermi electron gas under high compression.Â Keywords: Equation of state; High Pressure; Diborides.Â Â© 2009 JSR Publications.
