| Authors: | S. Yamaguchi H. Wada |
| Abstract: | A mixture of Fe3S4 (greigite) and FeS2 (pyrite) is formed at 200°C on hydrothermal treatment of freshly precipitated iron sulphide. Its electron diffraction diagramm was recorded, which corresponded to an incomplete solid solution of Fe3S4 and FeS2. The surface and the interior of the spherical particles of the samples (size about 500 Å) consisted of Fe3S4 and FeS2, respectively. |
