摘要：

Mossbauer spectroscopy has been used to investigate the solid phase transformation of goethite into hematite at 250-degrees-C. An Avrami-Erofeyev-type relation was found to describe the thermal conversion of alpha oxihydroxide to the alpha iron oxide. No intermediate phase was observed in the analyzed samples. The reaction constant was determined. A possible nucleation mechanism is also discussed.
