Synthesis and application of pigments based on lanthanide orthoferrites [PDF]

Processing and Application of Ceramics, 2020
In this work, we synthesized oxides with perovskite LnFeO3 type structure (where Ln = La, Pr and Nd), aiming their use as ceramic pigments. The as-synthesized powders, prepared by gelatin method, were thermally treated at 600 and 800 °C to obtain the ...
