The phase relations in the region of the Fe 2 O 3 ‐ and Al 2 O 3 ‐rich sides of the quaternary system SrO─Fe 2 O 3 –Al 2 O 3 –B 2 O 3 and the location of conjugation lines between magnetoplumbite solid solution SrO·(6 − x)Fe 2 O 3 ·xAl 2 O 3 and corundum (α‐Fe 2 O 3 , α‐Al 2 O 3 ) phases were determined at 1100°C in air by using the flux‐growth method based on the Ostwald ripening mechanism. Activity–composition relations and the lattice parameters along the magnetoplumbite solid solutions were also obtained.
