A Computational Look into Melting Predicts a Very High Melting Compound

This paper from Axel van de Walle’s group sounds interesting: Researchers predict material with record-setting melting point [see also this WaPo story]: The experimental record-holder is a substance made from the elements hafnium, tantalum, and carbon (Hf-Ta-C). But these new … Continue reading

Volume changes on melting

For most crystalline solids (in which the atoms/ions/molecules are packed tightly), we expect the density to fall on melting. This is somewhat easy to see for elemental metals. For example, the density of fcc Al falls from 2.7 g/cc to … Continue reading
