A study of the system Al 2 O 3 –Ga 2 O 3 –H 2 O has resulted in the determination of equilibrium diagrams for the systems Al 2 O 3 –Ga 2 O 3 and Al 2 O 3 .‐H 2 O–Ga 2 O 3 .H 2 O. Extensive solid solution characterizes the α ‐Al 2 O 3 and β ‐Ga 2 O 3 structures at high temperatures, but it is shown that below 810°C. a compound, GaAlO 3 , and a new series of (Al, Ga) 2 O 3 structures are stable. Among the hydrates, a complete series of diaspore solid solutions extends from Al 2 O 3 .H 2 O to Ga 2 O 3 .H 2 O. Boehmite solid solutions extend to approximately the composition 70Al 2 O 3 .H 2 O, 30Ga 2 O 3 .H 2 O.
