Sound velocity of liquid metals and metalloids at the melting temperature

摘要

In this article, we report a re-examination of the inter-relationship of the parameter (RTm/M)(0.5) and the velocity of sound c(m) at the melting temperature T-m for 41 liquid metals and metalloids. Sound velocities correlate with the equation c(m) = 7.5642(RTm/M)(0.5). Unknown sound velocities are estimated for as yet unmeasured liquid transition and lanthanide elements.
