摘要: Ba-M- and Sr-M-type hexagonal ferrites have been prepared via a sol–gel route, the effects of adding different amounts polyvinyl pyrrolidone (PVP) into sol solutions. The average crystallite, size, D σ, was obtained as for Z13 = 22 ± 2 nm Z13-2 16 3 nm Z16 18 7 nm Z16-2 17 5 nm by XRD. FT-IR TG analysis were used to prove presence PVP on BaFe12O19 SrFe12O19. Based TGA curves mass losses samples are assessed follows: ∼15%, ∼25%, ∼5%, ∼10%.
