“…To explain the observed effects, we propose an ion diffusion-catalytic mechanism of iron oxides' solid-phase reduction, detailing the provisions of the theory of V.E. Roshchin with colleagues [22][23][24][25][26] on the role of electronic processes in the iron oxides' reduction, adapted by us in relation to iron oxides of technogenic origin.…”

“…At reduction temperature of 1300 ºС only iron can be reduced from ilmenite grain, whereas titanium remains in the oxide phase. The propagation of the reduction process did not stop at the interface between solid carbon and ilmenite, and it proceeded in the entire volume of particles, which indicates the electron reduction mechanism and presence of anion ionic conductivity [20,21]. According to the electronic reduction mechanism the oxide crystal lattice which is presented by dense pack of oxygen anions has many defects, such as impurity defects and thermal defects.…”

“…очаге - в зоне фурм доменных печей и дуг в ферросплавных печах, во всех пирометаллургических агрегатах происходит эмиссия электронов с поверхности жидкого и твердого металла, нагретых до высокой температуры шихтовых материалов, особенно кокса, а также извести и офлюсованного агломерата, в которых содержится легко ионизируемый элемент кальций [42,43]. Эксперименты показали [44], что в слое шихтовых материалов плазма образуется даже при гарантированном отсутствии в углеродном материале летучих соединений, а также высокотемпературного очага.…”
