The Effects of Calcination Temperatures on Crystal Structures and Morphologies of Nd_1.2FeO₃Synthesized by Solid-State Reaction

Molten salt-directed synthesis of strontium manganese perovskite oxide: an active electrocatalyst for the oxygen reduction reaction and oxygen evolution reaction

“…The phase and compositional changes occur because the calcination temperature and heating time are not optimal to complete the reaction. 46 The alteration in the crystal system involves shrinkage/ stretching in the unit cell which induces a signicant strain in the materials. Furthermore, the crystallite size and microstrain were calculated using the Debye-Scherrer formula (D = Kl/b cos q) and Williamson-Hall plot (3 = b/4 tan q).…”

Synthesis of ytterbium-doped neodymium ferrite oxide using solid-state reaction method and its characterization

“…The Yb doped NdFeO 3 sample was synthesized using the best parameters found by previous research [18][19][20][21][22][23]. Raw materials of Nd 2 O 3 (Strem Chemicals, 99.99%), Yb 2 O 3 (Sigma-Aldrich, 99.99%) and Fe 2 O 3 (Sigma-Aldrich, 99.99%) were mixed according to stoichiometric calculation and grinded using mortar for 3 h. That mixed material then calcined using the furnace at temperature 700 C for 4 h. After that, the temperature increased to 950 °C by keeping the temperature constant for 2 h. The heating then decreased to 475 °C and kept it continued for 2 h. After this thermal process, the material was grinded for 6 h.…”
