Abstract: | A study of the system Al2O3–Ga2O3–H2O has resulted in the determination of equilibrium diagrams for the systems Al2O3–Ga2O3 and Al2O3.-H2O–Ga2O3.H2O. Extensive solid solution characterizes the α -Al2O3 and β -Ga2O3 structures at high temperatures, but it is shown that below 810°C. a compound, GaAlO3, and a new series of (Al, Ga)2O3 structures are stable. Among the hydrates, a complete series of diaspore solid solutions extends from Al2O3.H2O to Ga2O3.H2O. Boehmite solid solutions extend to approximately the composition 70Al2O3.H2O, 30Ga2O3.H2O. |
