Mechanosynthesis of the orthorhombic Perovskites ErMn1-xNi xO3 (x = 0, 0.1). processing and characterization of nanostructured ceramics

[EN] Because of the Jahn-Teller effect and low tolerance factor, the only reported method to obtain ErMnO3 materials with orthorhombic perovskite structure is to apply a high external pressure (on the order of GPa) at high temperature that transforms the stable room-temperature hexagonal structure t...

In this work, single-phase ErMnO3 and ErMn0.9Ni0.1O3 compositions with orthorhombic perovskite structure have been obtained for the first time by mechanosynthesis, after 24 h of milling in a tungsten carbide planetary mill. The high energy state achieved after the prolonged milling allows the perovskite structure to be isolated, instead of the habitual hexagonal one, without any external pressure. Subsequent thermal treatments transform the mechanosynthesized powder to the hexagonal structure at temperatures on the order of 1000 °C or higher. With the aim of obtaining ceramics with perovskite structure, spark plasma sintering (SPS) at 900 and 950 °C and 120 MPa was successfully tested.
