Phase formation, structural and microstructural characterization of novel oxynitride–perovskites synthesized by thermal ammonolysis of (Ca,Ba)MoO4 and (Ca,Ba)MoO3

Reactions of AMoO4 and AMoO3 (A=Ca2+, Ba2+) with ammonia were investigated at 873 K

Graphical abstractReactions of AMoO4 and AMoO3 (A=Ca2+, Ba2+) oxides with ammonia have been studied at T=873–1123 K. Orthorhombic CaMoO1.7(1)N1.3(1) (Pbnm) and cubic BaMo(O,N)3 (Pm3¯m) were prepared by thermal ammonolysis of the corresponding CaMoO3 and BaMoO3 precursors at T=898 and 998 K, respectively.Figure optionsDownload full-size imageDownload as PowerPoint slide
