Abstract: | A new series of mixed metals and squarates of formula [M(C4O4)(OH)(H2O)2]22H2O with (M=Al,Ga) has been synthesized, wen we report a work on the preparation of mixtures, the goal was to prepare a porous hybrid phase. But we obtained the phase prepared previously by J. T. Wobleski and D. B. Brown, thus of new phase belonging to the same family (Di[m-hydroxo-diaquo squarato of de trivalents metals). So we have also obtain this phase as well as with metal gallium (Ga) and aluminum (Al). The thermal decomposition of the precursors has been studied in vacuumbetween 100 and 600 °C, by powder thermodiffractometry for a compound of this family (M = Al) followed by a comparison between the temperature connect to thermal degradation of three compounds of this family. It is shown that crystalline intermediate phases are formed during the degradation. |
