| Experiments were performed utilizing the silica gel technique to synthesize pyrite crystals in four different chemical systems, at room temperature (;Six different iron (hydr)oxides show similar sulfidation behavior. Their reaction rates and products are dependent on pH and ;SEM observations indicate that the morphology of pyrite crystals formed at room temperature is primarily controlled by the degree of supersaturation in the solution from which pyrite is precipitated. At increased supersaturations, pyrite morphology changes from cube to octahedron then to spherulite. The influence of other parameters, such as pH, relative abundance of Fe... |
