Crystal lattice cohesion

The fact that the surface atoms in the plane of a crystal lattice surface possess the power of cohesion can also be demonstrated readily by such examples where clean pieces of platinum can be welded together, the joining of optically smooth glass surfaces and... 

What is implied by the observations in the preceding section is that the crystal lattices of substances of the IL type, in common with salt hydrate (and salt solvate crystals in general), become thermodynamically unstable with respect to their liquid phases (Guq < Gcrys) at temperatures that are very low, relative to their cohesive energies. 

What had been lacking was a general and cohesive quantitative treatment of crystal lattice reactions. Most quantita-... 

The cohesion of the atoms of a crystal lattice is determined by the energy that holds the atoms together and which is released when the crystal is disassembled into its atomic, molecular, or ionic components. It will be called the lattice energy or lattice enthalpy... 

Correction to the Sphericized Cell Calculation. (Paper 30) Wigner also worked out the correction to the spherical cell approximation in a cubic lattice. Here his previous work on cohesive energy in crystal lattices stood him in good stead, since the Wigner-Seitz method of calculation of cohesive energy also involved sphericizing a cubic cell. 

We may now regard the classification of crystal lattices on the basis of cohesive forces as closed and turn to the other classification which depends mainly on considerations of symmetry. It will appear in the course of the description how these two systems finally overlap and how, particularly in those lattices which have been discussed last, they supple-... 

In the solid state, the cohesive forces are stronger than the disrnptive forces (see > Figure 6.3A). Each particle of a crystalline solid ocenpies a fixed position in the crystal lattice (see Section 4.11). Disruptive kinetic energy canses the particles to vibrate about... 

The crystal binding, or cohesive energy, of single component molecular materials is often referred to as the lattice energy and can be calculated by summing all the interactions between a central molecule and aU the surrounding molecules in the crystal lattice (Docherty and Meenan 1999). Each atom-atom interaction pair consists of a van der Waals attractive and repulsive...
