L'objectif de ce travail concerne l'étude de l'amorphisation sous pression (PIA) dans des aluminophosphates, qui présentent des coefficients de expansion thermiques négatif (NTE). La synthèse de ces aluminophosphates, leur stabilité en température (dilatation) ainsi que leur comportement sous pression (amorphisationant) été étudiés. Les aluminophosphates choisis pour réaliser cette étude sont AlPO4-54, premier tamis moléculaire uniforme ayant des pores (unidimensionnelles parallèles à l'axe c) de diamètre supérieur à 1 nm, et AlPO4-17, qui présente une porosité tridimensionnelle et le plus fort coefficient de dilatation thermique négatif connu dans les matériaux oxydes. Chaque matériau déshydrataté a été étudié par diffraction des rayons-X...
