One of the polyols was polytetramethylene glycol (PTMEG) with molecular weight 1000 Da and it was chosen to obtain polyether diol-based polyurethanes (the typical formulation in the current internal coating for pipeline), and the other polyol was a copolymer of polycarbonate of 1,6-hexanediol and 1,5-pentanediol of molecular weight 500 Da--PCD--(Eternacoll[R] PH50, UBE Chemical Europe S.A., Castellon, Spain).

The formation mechanism can be attributed to reduction and Ostwald ripening: [Fe.sub.2][O.sub.3] submicrospheres are firstly synthesized; hematite is then reduced to magnetite and an incomplete layer consisted of [Fe.sub.3][O.sub.4] nuclei is formed on the solid [Fe.sub.2][O.sub.3] surfaces; a [Fe.sub.2][O.sub.3]-[Fe.sub.3][O.sub.4] core-cell structure is formed in the presence of 1,6-hexanediol; finally, [Fe.sub.3][O.sub.4] hollow submicrospheres are obtained through Ostwald ripening process.
