The melting of elemental solids is modeled as a dislocation-mediated transi
tion on a lattice. Statistical mechanics of linear defects is used to obtai
n a new relation between melting temperature, crystal structure, atomic vol
ume, and sheer modulus that is accurate to 17% for at least half of the Per
iodic Table. (C) 2000 Elsevier Science Ltd. All rights reserved.
