Barium oxide is essentially insoluble in BaO·6Fe 2 O 3 , and the nominal compositions BaO·5.5Fe 2 O 3 , and SrO·5.5Fe 2 O 3 used commercially may consist of the 1:6 phase and, respectively, one and two minor phases. Compacts formed by mechanical pressure filtration in a magnetic field are characterized by oriented aggregates of platy particles with planar faces and planar and curved edges. The preferred growth of faces and especially larger faces with curved edges leads to fewer edge‐face‐edge contacts and to a greater degree of collective orientation.
