Resume

Nous présentons une méthode de calcul de l'énergie totale d'une structure cristallińe (énergie électrostatique, énergie de van der Waals, et énergie de répulsion). Nous utilisons ensuite cette méthode pour étudier une série de phyllosilicates (talc, pyrophyllite, muscovite et phlogopite), pour comparer et discuter leurs propriétés physico-chimiques en particulier l'énergi de liaison interfoliaire et la distance interlamellaire. Nous constatons que des méthodes de calcul, basées sur des expressions empiriques différentes de l'énergie de répulsion, conduisent à des résultats relatifs analogues. Nous vérifions que la distance interlamellaire calculée approche la distance mesurée à 0·1 Å près. Nous calculons des énergies de liaison interfoliaire du talc et de la pyrophyllite (de l'ordre de 30 Kcal/mol) plus faibles que celles de la muscovite et de la phlogopite (de l'ordre de 60 Kcal/mol).

Abstract

Abstract

A calculation method for the total energy of a crystal structure (electrostatic, van der Waals and repulsion energies) is given. This is used to compare and discuss crystallochemical properties of talc, pyrophyllite, muscovite and phlogopite, in particular bonding energy and interlamellar distance. Different calculation methods based on different empirical formulae for the repulsion energy give closely similar results. The calculated interlamellar distances are within 0·1 Å of the measured distances. The bonding energy for talc and pyrophyllite (∼30 Kcal/mol) is weaker than that for muscovite and phlogopite (∼60 Kcal/mol).
