Thermodynamic stability of magnesium chromite from e.m.f. measurements

Electrochemical characterization of solid state reaction kinetics using voltammetry of microparticles. Application to thermal decomposition of iron chromites

“…This material is of considerable interest for metallurgy, cement and ceramic industry 19,20 where iron chromites are used as refractory and protective material for covering steel. [21][22][23][24] The electrochemical behaviour of chromites has attracted attention with regard to their thermal stability and thermochemical properties 25,26 and their possible use as electrocatalysts and electrodes for fuel cells, 27,28 and photoelectrocatalysts for H 2 generation. 29 In this context, the thermal stability of ferrous spinels in air has received attention with regard to the electrochemical applications of such materials.…”
