“…When the surface free energy of a solid is plotted as a function of temperature a discontinuity occurs at the melting point; the magnitude of the discontinuity is proportional to the latent heat of fusion.12, 13 The situation is expressed quantitatively by the following relation:…”

The occurrence of "metastable" tetragonal zirconia as a crystallite size effect is reviewed in the light of recently published experimental evidence. Evidence is presented to show this effect may be general and is a necessary consequence of a structural phase transformation associated with an endothermic heat effect during heating.Hydrostatic and nonhydrostatic stresses influence the microcrystal size-transformation temperature relationship profoundly. Consideration of the combined effects of these variables can account for all the experimental observations reported in the literature.

“…Generally the surface tension decreases with increasing undercooling (positive temperature coefficient), while an increasing surface tension with increasing undercooling (negative temperature coefficient) is observed more rarely. 86,87 The latter mainly occurs in glass formers around the glass transition temperature. While both phenomena can be described using analytical theories and modelling, [88][89][90] a full understanding of this broad variety is still desired.…”
