Thermophysical Properties of Stable and Supercooled Liquid Carbon

Аннотация

Temperature dependences of the isobaric heat capacity of stable and supercooled liquid carbon, which were obtained by processing thermograms of spontaneous cooling of spherical samples (levitation experiment), were determined. Using the thermodynamic analogy of the properties of the elements of the carbon subgroup of the Periodic Table for carbon, surface tension at the crystal–liquid interface, the size and the work of formation of the critical nucleus of the solid phase in a supercooled liquid, and the heat of fusion were found.
