MATERIALS AND METHODS FOR PREPARATION OF ALKALINE EARTH FERRATES FROM ALKALINE EARTH OXIDES, PEROXIDES, AND NITRATES

摘要

The subject invention concerns methods for preparing alkaline earth ferrates. In one embodiment, the alkaline earth ferrate is barium ferrate. In another embodiment, the alkaline earth ferrate is strontium ferrate. In one embodiment, methods of the invention comprise heat treating mixtures of alkaline earth oxides and/or peroxides with iron oxides, such as hematite or magnetite. In another embodiment, alkaline earth ferrates are produced by heating mixtures of alkaline earth nitrates and iron oxides. The subject invention also concerns hemostatic compositions produced using manganese oxides or metallic oxides that are reacted with alkaline earth oxides and/or peroxides and the methods used to produce the hemostatic compositions.
