Abstract

In the first part of the investigation the principle of galvanocoagulation process under condition of iron (steel-carbon (coke) galvanic coupling was described. In the St3-Fe^0-H_2O-O_2 systems, the ultradisperse (nanosized) iron oxide and oxyhydroxide minerals of different crystallographic modifications and spinel ferrites of 3d-metals can be obtained. The physicochemical conditions of the process carrying out influence on phase composition and type of ultradisperse structures. As initial structures formed in such systems Fe(II)-Fe(III) layered double hydtoxides (protolepidocrocite or Green Rust) and ferrihydrite which spring to develop α- and γ-morphological rows of iron-oxygen structures were shown.
