Metastable Materials Accessed under Moderate Pressure Conditions (P ≤ 3.5 GPa) in a Piston-Cylinder Press
In this review, we describe different families of metastable materials, some of them with relevant technological applications, which can be stabilized at moderate pressures 2–3.5 GPa in a piston-cylinder press. The synthesis of some of these systems had been previously reported under higher hydrosta...

description | In this review, we describe different families of metastable materials, some of them with relevant technological applications, which can be stabilized at moderate pressures 2–3.5 GPa in a piston-cylinder press. The synthesis of some of these systems had been previously reported under higher hydrostatic pressures (6–10 GPa), but can be accessed under milder conditions in combination with reactive precursors prepared by soft-chemistry techniques. These systems include perovskites with transition metals in unusual oxidation states (e.g., RNiO(3) with Ni(3+), R = rare earths); double perovskites such as RCu(3)Mn(4)O(12) with Jahn–Teller Cu(2+) ions at A sites, pyrochlores derived from Tl(2)Mn(2)O(7) with colossal magnetoresistance, pnictide skutterudites M(x)Co(4)Sb(12) (M = La, Yb, Ce, Sr, K) with thermoelectric properties, or metal hydrides Mg(2)MH(x) (M = Fe, Co, Ni) and AMgH(3) (A: alkali metals) with applications in hydrogen storage. The availability of substantial amounts of sample (0.5–1.5 g) allows a complete characterization of the properties of interest, including magnetic, transport, thermoelectric properties and so on, and the structural characterization by neutron or synchrotron X-ray diffraction techniques. |
