摘要: (1) Determinations have been made of structure type and lattice constants MnO, MnS, FeO Fe3O4 at temperatures near those which these substances show specific heat anomalies. (2) No major changes were apparent in the x‐ray patterns. All structures are cubic all investigated temperatures. Lattice constant data indicate similarity abnormal expansion behavior MnS MnO Fe3O4. (3) The anomalies probably due to electron transitions within certain atoms crystal may be analogous metallic iron 765°C, or quartz 575°C.
