摘要：

Hausmannite, Mn3O4, was synthesized by the hydrothermal oxidation of suspended Mn(OH)2 at ambient air at room temperature. The hausmannite exhibited thermal stability up to 250 °C. The formation of the Mn3O4 at such low-temperature regime avoids the undesirable effects of sintering on the surface accessibility. The low-temperature Mn3O4 assumes a relatively higher specific area than the Mn3O4(R) synthesized by calcination at 1050 °C.
