In this study, slowrelease silicon fertilizers are prepared from iron tailings by solidphase sintering and characterized by Xray diffraction (XRD) and scanning electron microscopy (SEM). The solubility results acquired from the optimal sample (SiIOT) indicate that the available SiO 2 is % and that of available K 2 O is % in mol L −1 HCl.
