Sr substituted materials for some barium in M-type barium ferrite powder and Co-Ti substituted Sr-Ba hexagonal ferrite powder were prepared by citrate sol-gel method and 2 MOE sol-gel method these hexaferrite particles were reduced for 1hr in the hydrogen gas. The reduction temperatures were varied in the range of 250 $^{circ}C$ to 500 $^{circ}C$. X-ray diffraction patterns were measured using diffractometer with Cu $K_{Alhpa}$ radiation. Mossbauer absorption spectra were measured with a constant acceleration spectrometer. We have focused on studying the origin of increasing $M_s$ by M$"{o}$ssbauer spectroscopy. Ferrite particles which were sintered at 105$0^{circ}C$ were found to be typical magnetoplumbite structure and single phase. XRD patterns with varying the reduction temperatures in $Sr_{0.5}Ba_{0.5}Fe_{10}O_{19}$ indicates ferrites particles become composite hexaferrites containing $alpha$-Fe at T_{red}=350 ;$^{circ}C$$</TEX>. On the otherhand, it was found that $Co^{2+}$ ions and $Ti^{4+}$ ions in $Sr_{0.7}Ba_{0.3}Fe_{10}CoTiO_{19}$ prevent from changing $Fe^{3+}$ ions to $alpha$-Fe during the $H_2$ reduction. Comparing Mossbauer results with XRD results, we have determined most of $alpha$-Fe are reduced from $4f_{vi}$ sites and 12k sites of $Fe^{3+}$ ions. These $alpha$-Fe phase bring the induced anisotropy and increase saturation magnetization $M_s$.TEX>.
