The Mechanical and Reaction Behavior of PTFE/Al/Fe2O3

FeO(OH) may be from the following reaction: Fe 2+ is probably derived from FeF 2, when contacting with O 2 and H 2 O in the air; Fe 2+ will be converted to FeO(OH) under some conditions. However, FeF 2 and FeO(OH) are all traceable, which have little effect on the energy release of the material, so they both can be regarded as impurity and can be ignored temporarily; the specific details will Get price

Phase Transformation of MnO2 and Fe2O3 Briquettes

The formation of ferromagnetic Mn x Fe 3−x O 4 with strong magnetism resulted in an inferior separation of manganese and iron by magnetization roasting-magnetic separation process. With the increase of CO content to over 25 vol%, the Mn x Fe 3−x O 4 content decreased while the content of feebly magnetic substance (MnO) y (FeO) 1−y (y = 0−1) increased. Get price
