Investigation of Thermodynamic Properties of Heavy Metals from Melting and Critical Point Properties
A statistical mechanical based equation of state has been employed to calculate the liquid density of lead, mercury, bismuth and lead-bismuth and lead-lithium eutectic alloys.The equation is basically that of Song, Mason and Ihm [Ihm G, Song Y, Mason EA. J. Chem. Phys.1991; 94: 3839] which is modified by Ghatee and Boushehri. Three temperature dependent parameters are required to use this e...
متن کاملThermodynamic origin of surface melting on ice crystals.
Since the pioneering prediction of surface melting by Michael Faraday, it has been widely accepted that thin water layers, called quasi-liquid layers (QLLs), homogeneously and completely wet ice surfaces. Contrary to this conventional wisdom, here we both theoretically and experimentally demonstrate that QLLs have more than two wetting states and that there is a first-order wetting transition b...
متن کاملMelting Point Determination
An improved technique is described for the accurate determination of melting points of metals in the temperature range 1500° to 2500°C. The improvements consist of gradient heating and refinements in cavity preparation to obtain true black-body conditions. The melting point of hafnium, as determined by this method, is set a t 22220-+30°C. This is over 200°C higher than one of the values reporte...

متن کاملHeat capacity of rare earth metals near the melting point and the vacancy mechanism of melting
The vacancy mechanism of the melting process is utilized as a starting point for deriving the formula for the difference of the heat capacity of the liquid and solid metal in the neighbourhood of the melting point. From these calculations it follows that the difference C,, C,, is the same for all the metals and equals 3.50 J g.atom-' K-'. This result is compared with the existing in the literat...
