On the other hand, inorganic coatings, such as phosphate materials [12], metallic or nonmetal oxides like SiO2 [13, 14], TiO2 [15], Al2O3 [16, 17], Fe3O4 [18], even Mn-Zn ferrite [19] and Ni-Zn...-silica. Only characteristic peak of α-Fe(Si) phase is observed in the XRD patterns of Fe-6.5Si powders coated with hybrid phosphate-silica and peaks of FePO4 and SiO2 are absent as shown in Figure 4......
