We study by hydrothermal synthesis between 200 and 500° C for ratios SiO₂/Al₂O₃ varied from 1 to 6, and Na₂O/Al₂O₃from 1 to 5. We observe that the pressure, always below 1 kbar, does not play a role in these conditions on the nature of the crystallized phases. The stability diagrams of analcite, cancrinite and albite are set out. We test specially the reversibility of the reactions and the boundaries of the diagrams.Ce système a été étudié en milieu hydrothermal entre 200 et 500° C, pour des domaines de concentrations variant de 1 à 6, pour SiO₂/Al₂O₃, et de 1 à 5 pour Na₂O/Al₂O₃. On constate que la pression toujours inférieure à 1 kbar, ne joue aucun rôle important, et on met en évidence les domaines de stabilité de nombreux minéraux dont ...
