Hydrothermal transformation of the calcium aluminum oxide hydrates CaAl2O4 dot 10H2O and Ca2Al 2O5 dot 8H2O to Ca3Al 2(OH)12 investigated by in situ synchrotron X-ray powder diffraction
The hydrothermal transformation of calcium aluminate hydrates were investigated by in situ synchrotron X-ray powder diffraction in the temperature range 25 to 170 degree C. This technique allowed the study of the detailed reaction mechanism and identification of intermediate phases. The material CaAl2O4*10H2O converted to Ca 3Al2(OH)12 and amorphous aluminum hydroxide. Ca2Al2 O5*8H2O transformed via the intermediate phase Ca4 Al2O7*13H 2O to Ca3Al2(OH)12 and gibbsite, Al(OH)3. The phase Ca4Al2O 7*19H2O reacted via the same intermediate phase to Ca3Al2(OH)12 and mainly amorphous aluminum hydroxide. The powder pattern of the intermediate phase is reported.
