“…In Figure 1, the pure components A, B, and C are located at the corners, and the formation of the compounds AB, AB 2 , CB, and AC is shown in their respective binary systems. One example found in the literature is the work by Grivel and Thyden, 42 who describe the ternary system SrO−In 2 O 3 −CuO at 900 °C in air, with analogous binary oxides such as Sr 2 CuO 3 , In 2 Cu 2 O 5 , SrIn 2 O 4 , SrCuO 2 , etc. at the three sides of the ternary system.…”
