Strukturmodell der Metallschmelze / Structural Model of Metal Melts

Abstract

The simple primitive rhombohedron with r1 as the shortest atomic distance of the close packing of spheres (structure I) and the square with the side r1′<r1 (structure II) are experimentally suggested to be the structural elements of metal melts. In the melts with metallic binding in the lattice the rhombohedron chain I shows up as a zigzag chain with the distances , r1, r1√3, r1√7, r1√12, r1√19, and so on in the atomic distribution curve, in the melts with homeopolar binding, however, the rhombohedron chain II appears as a straight chain with the distances rν= ν·r1. In both cases the square chains I and II of structure II yield straight chains with the distances r1′ and 2 r1′ as also rν′ = v·r1′. A schematic representation gives a rapid survey of the structure of monoatomic metal melts.
