Heating metal oxides
WebThe burning of steel means heating the steel very close to the solidus temperature (which is always avoided) and manifests as a layer of partially oxidised steel lying under the layer of scale, and where oxygen has penetrated along the grain boundaries of the steel and where, it causes not only decarburisation but formation of iron oxide. WebMetal oxides with different structures, such as rock salt oxides, perovskite oxides, and so on, were synthesized by Joule heating, achieving rapid structural screening. Meanwhile, Fe, Mn, Ni, Zn, and Mg were also successfully doped in metal oxides, significantly improving the OER and ORR performance of CoO.
