Influence of temperature and oxygen pressure on the stability of barium or strontium doped neodymium manganites
Autor: Larisa Vedmid', Olga Fedorova, Valentina Balakireva, Vladimir Balakirev
Publikováno v: Processing and Application of Ceramics, Vol 14, Iss 3, Pp 203-209 (2020)
In this work neodymium manganites, Nd1-xAxMnO3±δ, doped with Ba or Sr (where x = 0.15 and 0.25) were obtained by ceramic technology at 1250 °C. In order to obtain materials with stable thermal and electrical properties, their structure and physico

Mechanism of Ion-Diffusion Solid-Phase Reduction of Iron Oxides of Technogenic Origin in the Presence of the Liquid Phase and without it
Autor: Oleg Sheshukov, Mikhail Mikheenkov, Larisa Vedmid’, Iliya Nekrasov, Denis Egiazaryan
Publikováno v: Metals, Vol 10, Iss 12, p 1564 (2020)
The processes of iron oxides’ reduction have a complex physicochemical mechanism, with the participation of solid, liquid, and gaseous substances. The article discusses the existing models for the reduction of iron oxides and provides data on the t
