Synthesis of the FeS₂ (pyrite) powders via a solvent-thermal process is reported. Using FeSO₄ and NH₂CSNH₂ as precursors and polyvinylpyrrolidone (PVP) as a protective agent (dispersant), high purity FeS₂ powders have been synthesized by reaction in alcohol-water solution at 200 ℃ for 36 h. The experiment result shows that, single-phase pyrite powders can be obtained both in acid environment (pH=5) and in alkali environment (pH=10). Effects of pH value on pyrite powder structure, crystallite size and optical characterization are discussed.
