Ferrochromite
WebOct 17, 2016 · The gadolinium ferrochromite (GdFe 1−x Cr x O 3) was used as a case study of influence of chromium substitution on the perovskite structure in the entire composition range.By exploiting thermal analysis techniques (dilatometry, differential thermal analysis) the influence of chromium was investigated in the context of thermal … WebAbstract. We previously mentioned the possibility of preparing polycrystalline Mg-Mn ferrochromite films by Chemical Transport Deposition (CTD) using HCl as a reaction gas. 1 The thermodynamic calculations, however, indicated that the ferrochromite chemical transport should be enchanced when using chlorine Cl 2 in place of HCl. The aim of this …
